ATTENTION all CAM member tube shoppers...
Finding the right tube for your amp/pre amp,you will find that there will be a lot of different opinions ....
Many times all the answers are right.
The complications can be is some tubes can be very system dependent so it will depend on your system as to which tubes sound the best.
We all desire quiet nice sounding tubes.
Why are some tubes noisier then others,or quieter in certain amps and not in others?
Audio tubes need to settle in and then will get better once burned in.
Definitely buy from a reputable dealers!
If you're going to be into tubes, its always beneficial to develop a relationship with dealers you can trust.
If you want to find the best sounding tube for your system and don't mind spending $$, then buy several brands/types and listen for yourself.
Each brand tends to feature characteristics that may appeal to you and match well with your unit, others not so much so there really isn't one 'best-sounding' tube out there as its very dependent on the application.
Also, while these super rare and uber-expensive tubes do sound great, they're best implementation is in sensitive pre amps and phono stages Remember, a good portion of their cost can be attributed to their scarcity, not just their sonics.
They really don't stand out in the usual amplifier's driver stage and in most other gear, a similar but substantially more common NOS tube of the same manufacturer will provide all but maybe the last 1% of the sonics of the super tubes at a much lower price.
Although improving, still many of the new tubes made today in Europe, China and Russia only reproduce random varied harmonics.
This can be why most of us upgrades to a vintage made tube made decades ago when these rare inner earth metals were available in the inside construction of the vintage tube.
These metals have become too expensive to use and today’s tube makers have found cheaper substitutes which seem to work but do not reproduce all the nuances and textures in music! ...

*Also have some very nice and quiet 5963 which is a MEDIUM-MU TWIN TRIODE. 9—PIN MINIATURE TYPE
Very little is written about these 5963 tubes.
It's practically today unknown, yet these are excellent fantastic replacements for 12AU7 tubes!
Smooth and sweet,yet bargain priced compared with many European brands!
Very smooth tube from top to bottom with no weakness!
These are a nice industrial/military upgrade variant type which is nearly identical to the standard 12AU7.
RCA made a nice black plate version of this tube
The 1950’s RCA 5963 sounds more dynamic than the standard 12AU7 Blackplate
It’s also a very good low-noise tube.
GE has it in their broadcast line.
The plate voltage rating is a little lower than for a 12AU7, but for most applications, it will work fine.
It has a rugged cathode and should be quite long lived, similar to the 5814.
That specially-designed cathode is said to withstand long periods of time in cut-off without damaging the tube (cathode poisoning).
This made them a great choice for NORAD computers, which led to a good supply of them on the USA West Coast.
Use them and you will marvel at the quality and value.
They are dead-silent and seem to have an unusually long lifespan.
Very satisfied with the sound they produce.
A truly fine 12AU7 variant from the 1950's, many tube audiophiles feel these can outperform most other NOS 12AU7 tubes!
In computer (and some other) service, tubes were quite often operated as switches, biased to cutoff (no plate current) for long periods of time and then turned on, while always the heater and cathode were warmed up and ready to go.
In ordinary tubes, this leads to a condition known as "cathode interface resistance" or "sleeping sickness."
The cathode interface is a layer of metal, usually nickel, between the cathode sleeve and the oxide coating that emits electrons. In ordinary tubes, under conditions of long-duration tube cutoff, it generates a growing resistance until at last the cathode "goes to sleep."
Computer tube cathodes were specially treated to survive those long periods of cutoff without developing cathode interface resistance

12AT7 / 12AU7 Tubes BALDWIN / GE / PHILIPS / RCA / ROGERS / SYLVANIA / WESTINGHOUSE

The 12AU7, 12BH7, and 6CG7 have very similar electrical characteristics and can usually be substituted for each other.

12AU7 is identical to a 6CG7 electrically and in the circuit it will function identically. However, there is a different heater pin out.
So if you are substituting you need to make a change.
In addition, the 6CG7 draws twice as much heater current so be sure that this will work in your circuit. (This may be one reason it is not as popular as it should be.)

12BH7 requires no circuit modification to substitute for a 12AU7, but the plate resistance is a little lower (5300 vs 7700).
Thus, even though it has a lower u (or amplification factor), the gain may be slightly higher depending on the circuit design.
[This is mainly true for circuits that use an anode resistor load.]
It will also draw a little more current, but the 12BH7 is a beefier tube and can handle it.
For most circuits this should be well within the tolerances of the design, but you can ask the manufacturer to be sure.
With respect to audio reproduction there is a fairly large difference between these three tubes.
The 6CG7 (or 6FQ7 which is the same exact tube) is identical in internal construction to the 6SN7. The 6SN7 has the reputation of being the most linear of the medium mu triodes and the 6CG7 follows suit.
Also, the 6CG7 line is remarkably similar in audio performance across various manufacturers of the same vintage or age.
It is a good tube for early or middle stage amplification and has the added bonus of a grounded shield between sections, which reduces hum and increases channel separation.

The 12BH7 can lend a wonderful life to the tone that sounds great for jazz or vocals. For audio listening, this tube can temper the harshness of CD's.
There is, however, a wider variation in the sound of 12BH7s than 6CG7s, so some tube selection or rolling is in order.
You can find very neutral 12BH7s (watch for a coming blog comparing them) . If you don't want to modify the circuit and are unhappy with your 12AU7--this is a good choice.

The 12AU7 family has the widest variety of tonal characteristics which is probably why this tube is rolled so often by audiophiles.
Personally I find some 12AU7s a little tinny in comparison with the 12BH7 and 6CG7, but there are exceptions,such as RCA clear tops and 5963 tubes!

Part of the fun and magic of tubes is rolling them when listening to different types of music.

*Also have some very nice and quiet 5963 which is a MEDIUM-MU TWIN TRIODE. 9—PIN MINIATURE TYPE
Very little is written about these 5963 tubes.
It's practically today unknown, yet these are excellent fantastic replacements for 12AU7 tubes!
Smooth and sweet,yet bargain priced compared with many European brands!
Very smooth tube from top to bottom with no weakness!
These are a nice industrial/military upgrade variant type which is nearly identical to the standard 12AU7.
RCA made a nice black plate version of this tube
The 1950’s RCA 5963 sounds more dynamic than the standard 12AU7 Blackplate
It’s also a very good low-noise tube.
GE has it in their broadcast line.
The plate voltage rating is a little lower than for a 12AU7, but for most applications, it will work fine.
It has a rugged cathode and should be quite long lived, similar to the 5814.
That specially-designed cathode is said to withstand long periods of time in cut-off without damaging the tube (cathode poisoning).
This made them a great choice for NORAD computers, which led to a good supply of them on the USA West Coast.
Use them and you will marvel at the quality and value.
They are dead-silent and seem to have an unusually long lifespan.
Very satisfied with the sound they produce.
A truly fine 12AU7 variant from the 1950's, many tube audiophiles feel these can outperform most other NOS 12AU7 tubes!
In computer (and some other) service, tubes were quite often operated as switches, biased to cutoff (no plate current) for long periods of time and then turned on, while always the heater and cathode were warmed up and ready to go.
In ordinary tubes, this leads to a condition known as "cathode interface resistance" or "sleeping sickness."
The cathode interface is a layer of metal, usually nickel, between the cathode sleeve and the oxide coating that emits electrons. In ordinary tubes, under conditions of long-duration tube cutoff, it generates a growing resistance until at last the cathode "goes to sleep."
Computer tube cathodes were specially treated to survive those long periods of cutoff without developing cathode interface resistance

ATTENTION all CAM member tube shoppers...
Finding the right tube for your amp/pre amp,you will find that there will be a lot of different opinions ....
Many times all the answers are right.
The complications can be is some tubes can be very system dependent so it will depend on your system as to which tubes sound the best.
We all desire quiet nice sounding tubes.
Why are some tubes noisier then others,or quieter in certain amps and not in others?
Audio tubes need to settle in and then will get better once burned in.
Definitely buy from a reputable dealers!
If you're going to be into tubes, its always beneficial to develop a relationship with dealers you can trust.
If you want to find the best sounding tube for your system and don't mind spending $$, then buy several brands/types and listen for yourself.
Each brand tends to feature characteristics that may appeal to you and match well with your unit, others not so much so there really isn't one 'best-sounding' tube out there as its very dependent on the application.
Also, while these super rare and uber-expensive tubes do sound great, they're best implementation is in sensitive pre amps and phono stages Remember, a good portion of their cost can be attributed to their scarcity, not just their sonics.
They really don't stand out in the usual amplifier's driver stage and in most other gear, a similar but substantially more common NOS tube of the same manufacturer will provide all but maybe the last 1% of the sonics of the super tubes at a much lower price.
Although improving, still many of the new tubes made today in Europe, China and Russia only reproduce random varied harmonics.
This can be why most of us upgrades to a vintage made tube made decades ago when these rare inner earth metals were available in the inside construction of the vintage tube.
These metals have become too expensive to use and today’s tube makers have found cheaper substitutes which seem to work but do not reproduce all the nuances and textures in music! ...

ATTENTION all CAM member tube shoppers...
Also have some very good 5963 tubes!
Just wait until you listen to all the types of 5963's.
It's another 12AU7A variant.
The 5963 IS A MEDIUM-MU TWIN TRIODE. 9—PIN MINIATURE TYPE
A variant of the 12AU7 family of tubes
Very little is written about these 5963 tubes.
It's practically today unknown, yet these are excellent fantastic replacements for 12AU7 tubes!
Smooth and sweet,yet bargain priced compared with many European brands!
Very smooth tube from top to bottom with no weakness!
These are a nice industrial/military upgrade variant type which is nearly identical to the standard 12AU7.
RCA made a nice black plate version of this tube
The 1950’s RCA 5963 sounds more dynamic than the standard 12AU7 Blackplate
It’s also a very good low-noise tube.
Sylvania has a gold pin version, and GE has it in their 5-star broadcast line.
The plate voltage rating is a little lower than for a 12AU7, but for most applications, it will work fine.
It has a rugged cathode and should be quite long lived, similar to the 5814.
That specially-designed cathode is said to withstand long periods of time in cut-off without damaging the tube (cathode poisoning).
This made them a great choice for NORAD computers, which led to a good supply of them on the USA West Coast.
Use them and you will marvel at the quality and value.
They are dead-silent and seem to have an unusually long lifespan.
Very satisfied with the sound they produce.
A truly fine 12AU7 variant from the 1950's, many tube audiophiles feel these can outperform most other NOS 12AU7 tubes!
In computer (and some other) service, tubes were quite often operated as switches, biased to cutoff (no plate current) for long periods of time and then turned on, while always the heater and cathode were warmed up and ready to go.
In ordinary tubes, this leads to a condition known as "cathode interface resistance" or "sleeping sickness."
The cathode interface is a layer of metal, usually nickel, between the cathode sleeve and the oxide coating that emits electrons. In ordinary tubes, under conditions of long-duration tube cutoff, it generates a growing resistance until at last the cathode "goes to sleep."
Computer tube cathodes were specially treated to survive those long periods of cutoff without developing cathode interface resistance

The 12AU7 is a miniature medium-mu twin triode. This tube finds use as a phase-inverter/splitter in push-pull amplifier circuits in ac/dc radio equipment and in many diversified applications such as multivibrators or oscillators in industrial control devices. The tube is quite pokey and sections can even be connected in parallel to create a power amp with enough current to drive a pair of headphones or even a guitar speaker. A centre tapped heater permits operation of the tube from a 6.3V or a 12.6V heater supply. The tube requires a noval nine-contact socket and may be mounted in any position.

12AU7 tube equivalents:
12AU7/12AU7A: The common U.S.A. version of this tube.
The 12AU7 can only be used in parallel filament circuits. Like the 12AX7, this is not a hassle since virtually all hi-fi tube amps are of the parallel filament design. RCA, GE, and Sylvania actually made most of these tubes, regardless of brand on the label. The early RCA version has ribbed flat black plates with a top getter and a white label. This is an amazing tube, one of the best USA 12AU7 tubes ever made and we have a good stock of these. Still available, and still a bargain since everyone wants the “cleartops”: 1960s versions that have grey-plates and the getter on the side, making the top clear. These “cleartops” are currently the hottest selling 12AU7, and are still a great buy at current prices. Watch this tube….I predict in 5 years it will be as hard to find as the Telefunken smoothplate, and just as expensive! The 1970s new logo version (and the late 1940s-1950s version with the white label) of the RCA 12AU7 has greyplates and a top getter. This grey-plate RCA is about the best bargain you can get in a vintage RCA 12AU7. The GE versions pretty much always used grey-plates and a top getter for this tube. The numbers are etched into the glass with a pattern of dots below the number. Don’t miss trying the “organ stock” 12AU7 tubes that were sold to organ manufacturers. These sweet tubes were screened for audio use in organs, and have the organ brand on the label. Usually sold at bargain prices because of the re-branded label, the RCA cleartop and Raytheon blackplate versions are a great find! Tung Sol made an early “blackglass” version in the late 1940s, which hides the inside of the tube from view, and is very rare; later Tung Sol 12AU7 tubes look like early RCA grey-plates inside. All of these vintage tubes used a chalky label paint, and often the tube label is smeared or partially rubbed off. This does not indicate use or poor quality. Rather, it is an indication of a genuine vintage tube, and all of these are excellent quality.
ECC82: This is the European version of the 12AU7, and is identical to it. The brands in demand are Telefunken, Amperex, and Mullard. Telefunken tubes have a diamond shape molded into the bottom of the glass. Both ribbed plate and the more famous smooth-plate types are available, just like the 12AX7, but are being hunted down and soon may be an endangered species. Amperex and Mullard have tiny date codes etched in the glass near the bottom of the tube. The most popular Amperex are the Holland made Bugle Boy series, with the tiny cartoon tube blowing a bugle on the label. They later went to just a white label that said “Amperex”, and then after that used the orange label with the world logo. The earlier Mullard tubes had the word “Mullard” inside of a shield logo, later versions said “IEC Mullard”. Watch for the very rare long plate versions from the 1950s available in most European brands. These had narrow plates that were about 3mm longer than the 1960s and later versions. The earliest had square shape top getter elements, late long-plates have a halo top getter. Even rarer are the Mullard and Amperex made CV491 longplate square getter tubes, made only for the military. Most of these early Mullard tubes can be spotted not only by the date codes and longplates, but by the distinctive “wrinkle” glass, where the surface of the glass tube is not smooth but rather has tiny wrinkles or sometimes an eggshell texture. These are all tubes of unequalled quality, and are worth the high prices they are commanding these days. Even used ones will blow away any of the trashy tubes in production today. Vintage versions again used the chalky paint, and frequently the labels on any of these tubes are usually smeared.
CV491: A military specification version of the ECC82. These are usually found in Mullard or Brimar versions, but I have seen Siemens as well, and some made by Amperex. This tube was made into the 1990s so careful selection needs to be made. The best are the Mullard and Amperex longplates from the 1950s, which look identical to the longplate ECC82. Ei Yugoslavia made a nice smoothplate version into the late 1980s which sounds surprisingly good despite it’s late vintage “East Europe” stigma attached to it. Overall, these are a step up from the standard ECC82 tubes, since they have military specs.
5814: This is a military spec tube. Sometimes the vintage GE versions may be labelled JG-12AU7WA in white and have 5814 etched into the glass. These are all low microphonic thanks to their rigid mica supports. Older versions have a third mica spacer near the top. These “triple mica” versions are in great demand today. The broadcast versions of this tube are the GE 5-star, and the RCA Command series. These vintage tubes have just started to become a hot item, as N.O.S. stocks of the West Europe types become harder to find. These tubes can withstand many on-off cycles and mechanical shock without a problem.
6189/E82CC: This can be both a military spec tube and a premium industrial tube. Often, the military versions will be marked 12AU7WA in addition to having 6189 etched in the glass. The older vintage of these tubes are usually black-plate with the extra “triple mica” spacer at the top. GE made this in their 5-star line for broadcast. The RCA military 6189 is gold lettered 12AU7WA, has black-plates, and extra support rods. These are excellent step up tubes in the 12AU7 family, when you can find them! Look for super rare triple mica versions from Mazda, Siemens, and Mullard, some with silver plates. Among the best 12AU7 tubes ever made.
5963: This is a nice industrial type which is nearly identical to the standard 12AU7. RCA made a nice black-plate version of this tube, Sylvania has a gold pin version, and GE has it in their 5-star broadcast line. The plate voltage rating is a little lower than for a 12AU7, but for most applications, it will work fine. It has a rugged cathode and should be long lived, similar to the 5814. Watch this tube, as it is plentiful now and prices are low. As audiophiles discover it, the rush will be on!
6350: This tube was mainly manufactured for IBM and other computers in the late 1950s to mid 1960s. Sylvania and GE blackplates are considered the best of all with this tube. The only difference is the pins that correspond to the grid and plate of each triode are reversed from the 12AU7 connections, so you will either need to rewire your sockets to take this tube, or consult with the manufacturer of your unit to see if this tube can be used as a sub for the 12AU7. It has a mu or gain factor of 18 so is very close to the 12AU7. These were made to tight specs and carefully quality checked, since replacement in a computer of the day was difficult and costly, and the tubes were expected to operate 24-7. These make impressive upgrades to the standard 12AU7!
6680: Motorola and GE are the brands you find most often with this tube, but RCA made a nice cleartop version for a very short time. It is identical to the 12AU7, but has the added benefit of being able to withstand variations in filament voltage without affecting it’s output. This tube was designed originally for two-way mobile radio use. It makes a fine hi-fi 12AU7 tube as well. Never as plentiful as other types, this tube is rather scarce today.
7730: An excellent USA made industrial version of the 12AU7, produced mainly by CBS labs but I have seen it with other labels as well. This tube has thickly plated gold pins and was designed for critical aircraft and other exacting industrial applications. It has a long life heater, is extremely well balanced and a top choice for audio use. Very rare today.
ECC802: This is a premium version of the European ECC82, with matched triode sections. These are very rare in the USA, and often command very high prices.
E80CC/6085: This unusual European tube is basically an industrial type 6085. However, it’s specs are similar enough to a 12AU7 that audiophiles are grabbing them up while the prices are still reasonable. The heater life is rated at 10,000 hours, and some have gold pins. The larger box plate structure gives this tube low microphonics and silky smooth sonics. Some of the Philips Holland versions had the rare pinched waist, where the glass dips inward and actually molds around the top mica plate, giving the plates extra support and virtually eliminating microphonics. There is also a version made at the Amperex factory in Hicksville, NY, which is often priced lower but looks the same and sounds very similar to the Holland version. Since this tube has a much higher Gm and Mu factor than a 12AU7, the gain is going to be greater and this tube will give a more forward presentation. Awesome in phase splitter applications. If in doubt, check with your amp or preamp manufacturer to see if this tube will work OK in your application. This tube is also about twice as tall as a 12AU7, so installation space in your chassis is a consideration as well. These are out of production, rare, and getting very hard to find. The European types usually command the top prices, but U.S.A. types exist as the 6085 and should be a bit lower in cost, but they are also rare and climbing in price. Many U.S.A. tubes were actually made by the European factories, so watch for the 6085 U.S.A. brands!
B749: This is made by Genalex (Marconi-Osram Valve Co. of England) and is extremely rare in the U.S.A. The B749 is in the “Gold Lion” series of audiophile tubes, and has the gold lion and gold script on the glass. Inside it looks similar to a Mullard 12AU7, and has a red Genalex decal across the bottom. These are said to sound the best of all 12AU7 types, and this reputation, coupled with it’s overall scarcity, has driven the market price of this prize tube to extreme heights. Worth seeking out as these may be the first out-of-production classic European tube to go totally extinct over the next dozen years or so.

The 12AU7, 12BH7, and 6CG7 have very similar electrical characteristics and can usually be substituted for each other.

12AU7 is identical to a 6CG7 electrically and in the circuit it will function identically. However, there is a different heater pin out.
So if you are substituting you need to make a change.
In addition, the 6CG7 draws twice as much heater current so be sure that this will work in your circuit. (This may be one reason it is not as popular as it should be.)

12BH7 requires no circuit modification to substitute for a 12AU7, but the plate resistance is a little lower (5300 vs 7700).
Thus, even though it has a lower u (or amplification factor), the gain may be slightly higher depending on the circuit design.
[This is mainly true for circuits that use an anode resistor load.]
It will also draw a little more current, but the 12BH7 is a beefier tube and can handle it.
For most circuits this should be well within the tolerances of the design, but you can ask the manufacturer to be sure.
With respect to audio reproduction there is a fairly large difference between these three tubes.
The 6CG7 (or 6FQ7 which is the same exact tube) is identical in internal construction to the 6SN7. The 6SN7 has the reputation of being the most linear of the medium mu triodes and the 6CG7 follows suit.
Also, the 6CG7 line is remarkably similar in audio performance across various manufacturers of the same vintage or age.
It is a good tube for early or middle stage amplification and has the added bonus of a grounded shield between sections, which reduces hum and increases channel separation.

The 12BH7 can lend a wonderful life to the tone that sounds great for jazz or vocals. For audio listening, this tube can temper the harshness of CD's.
There is, however, a wider variation in the sound of 12BH7s than 6CG7s, so some tube selection or rolling is in order.
You can find very neutral 12BH7s (watch for a coming blog comparing them) . If you don't want to modify the circuit and are unhappy with your 12AU7--this is a good choice.

The 12AU7 family has the widest variety of tonal characteristics which is probably why this tube is rolled so often by audiophiles.
Personally I find some 12AU7s a little tinny in comparison with the 12BH7 and 6CG7, but there are exceptions,such as RCA clear tops and 5963 tubes!

Part of the fun and magic of tubes is rolling them when listening to different types of music.

*Also have some very nice and quiet 5963 which is a MEDIUM-MU TWIN TRIODE. 9—PIN MINIATURE TYPE
Very little is written about these 5963 tubes.
It's practically today unknown, yet these are excellent fantastic replacements for 12AU7 tubes!
Smooth and sweet,yet bargain priced compared with many European brands!
Very smooth tube from top to bottom with no weakness!
These are a nice industrial/military upgrade variant type which is nearly identical to the standard 12AU7.
RCA made a nice black plate version of this tube
The 1950’s RCA 5963 sounds more dynamic than the standard 12AU7 Blackplate
It’s also a very good low-noise tube.
GE has it in their broadcast line.
The plate voltage rating is a little lower than for a 12AU7, but for most applications, it will work fine.
It has a rugged cathode and should be quite long lived, similar to the 5814.
That specially-designed cathode is said to withstand long periods of time in cut-off without damaging the tube (cathode poisoning).
This made them a great choice for NORAD computers, which led to a good supply of them on the USA West Coast.
Use them and you will marvel at the quality and value.
They are dead-silent and seem to have an unusually long lifespan.
Very satisfied with the sound they produce.
A truly fine 12AU7 variant from the 1950's, many tube audiophiles feel these can outperform most other NOS 12AU7 tubes!
In computer (and some other) service, tubes were quite often operated as switches, biased to cutoff (no plate current) for long periods of time and then turned on, while always the heater and cathode were warmed up and ready to go.
In ordinary tubes, this leads to a condition known as "cathode interface resistance" or "sleeping sickness."
The cathode interface is a layer of metal, usually nickel, between the cathode sleeve and the oxide coating that emits electrons. In ordinary tubes, under conditions of long-duration tube cutoff, it generates a growing resistance until at last the cathode "goes to sleep."
Computer tube cathodes were specially treated to survive those long periods of cutoff without developing cathode interface resistance

ATTENTION all CAM member tube shoppers...
Finding the right tube for your amp/pre amp,you will find that there will be a lot of different opinions ....
Many times all the answers are right.
The complications can be is some tubes can be very system dependent so it will depend on your system as to which tubes sound the best.
We all desire quiet nice sounding tubes.
Why are some tubes noisier then others,or quieter in certain amps and not in others?
Audio tubes need to settle in and then will get better once burned in.
Definitely buy from a reputable dealers!
If you're going to be into tubes, its always beneficial to develop a relationship with dealers you can trust.
If you want to find the best sounding tube for your system and don't mind spending $$, then buy several brands/types and listen for yourself.
Each brand tends to feature characteristics that may appeal to you and match well with your unit, others not so much so there really isn't one 'best-sounding' tube out there as its very dependent on the application.
Also, while these super rare and uber-expensive tubes do sound great, they're best implementation is in sensitive pre amps and phono stages Remember, a good portion of their cost can be attributed to their scarcity, not just their sonics.
They really don't stand out in the usual amplifier's driver stage and in most other gear, a similar but substantially more common NOS tube of the same manufacturer will provide all but maybe the last 1% of the sonics of the super tubes at a much lower price.
Although improving, still many of the new tubes made today in Europe, China and Russia only reproduce random varied harmonics.
This can be why most of us upgrades to a vintage made tube made decades ago when these rare inner earth metals were available in the inside construction of the vintage tube.
These metals have become too expensive to use and today’s tube makers have found cheaper substitutes which seem to work but do not reproduce all the nuances and textures in music! ...

Also have 4 x Marconi 6AV5 GA Output tubes @ $80.00 for all 4 tubes including shipping to anywhere in Canada!

Clearing out many assorted brands of vintage 1950 -60's
ECC82 / 12AU7 + ECC83 / 12AX7 ECC81 / 12AT7 tubes
Excellent pairs of BALDWIN organ grade tubes, chosen for and sold to Baldwin Organ.
These date from the early 1960's.
Organ grade tubes were tooled to be very quiet musical 12AU7 tubes!
Payable by EMT, if Paypal + 4%
Price is per matched pairs @ $70.00/pair

Also we have these 12AT7 RCA Black Plate tubes @ $25.00 each
The 12AT7 has a mu factor of 60.
Each triode section of the tube acts as a class A amplifier.
Because of this, the tubes can be used in microphone preamplifiers, instrument amps, and recording equipment that is equipped with vacuum tubes. The tube features a double triode with separate cathodes, and because of their design, they are low noise.
They requires a noval nine-contact socket, but can be mounted in any position.
Nice and quiet,excellent tone, dynamics and clarity!
Test strong!

Mostly are G.E. / Marconi / RCA / Sylvania / Westinghouse
Both short or long grey + black plates are available.
Test strong like new with very closely matched sections.
All have had very little use.
Lettering and logo prints are all excellent!
All these vintage tubes still do test very strong, like new /very close!
All tubes have been tested twice on my mutual conductance calibrated B+K tester
They will test at or close to new.

*Also have some very nice and quiet 5963 which is a MEDIUM-MU TWIN TRIODE. 9—PIN MINIATURE TYPE
Very little is written about these 5963 tubes.
It's practically today unknown, yet these are excellent fantastic replacements for 12AU7 tubes!
Smooth and sweet,yet bargain priced compared with many European brands!
Very smooth tube from top to bottom with no weakness!
These are a nice industrial/military upgrade variant type which is nearly identical to the standard 12AU7.
RCA made a nice black plate version of this tube
The 1950’s RCA 5963 sounds more dynamic than the standard 12AU7 Blackplate
It’s also a very good low-noise tube.
GE has it in their broadcast line.
The plate voltage rating is a little lower than for a 12AU7, but for most applications, it will work fine.
It has a rugged cathode and should be quite long lived, similar to the 5814.
That specially-designed cathode is said to withstand long periods of time in cut-off without damaging the tube (cathode poisoning).
This made them a great choice for NORAD computers, which led to a good supply of them on the USA West Coast.
Use them and you will marvel at the quality and value.
They are dead-silent and seem to have an unusually long lifespan.
Very satisfied with the sound they produce.
A truly fine 12AU7 variant from the 1950's, many tube audiophiles feel these can outperform most other NOS 12AU7 tubes!
In computer (and some other) service, tubes were quite often operated as switches, biased to cutoff (no plate current) for long periods of time and then turned on, while always the heater and cathode were warmed up and ready to go.
In ordinary tubes, this leads to a condition known as "cathode interface resistance" or "sleeping sickness."
The cathode interface is a layer of metal, usually nickel, between the cathode sleeve and the oxide coating that emits electrons. In ordinary tubes, under conditions of long-duration tube cutoff, it generates a growing resistance until at last the cathode "goes to sleep."
Computer tube cathodes were specially treated to survive those long periods of cutoff without developing cathode interface resistance

The 12AU7, 12BH7, and 6CG7 have very similar electrical characteristics and can usually be substituted for each other.
12AU7 is identical to a 6CG7 electrically and in the circuit it will function identically. However, there is a different heater pin out.
So if you are substituting you need to make a change.
In addition, the 6CG7 draws twice as much heater current so be sure that this will work in your circuit. (This may be one reason it is not as popular as it should be.)

12BH7 requires no circuit modification to substitute for a 12AU7, but the plate resistance is a little lower (5300 vs 7700).
Thus, even though it has a lower u (or amplification factor), the gain may be slightly higher depending on the circuit design.
[This is mainly true for circuits that use an anode resistor load.]
It will also draw a little more current, but the 12BH7 is a beefier tube and can handle it.
For most circuits this should be well within the tolerances of the design, but you can ask the manufacturer to be sure.
With respect to audio reproduction there is a fairly large difference between these three tubes.
The 6CG7 (or 6FQ7 which is the same exact tube) is identical in internal construction to the 6SN7. The 6SN7 has the reputation of being the most linear of the medium mu triodes and the 6CG7 follows suit.
Also, the 6CG7 line is remarkably similar in audio performance across various manufacturers of the same vintage or age.
It is a good tube for early or middle stage amplification and has the added bonus of a grounded shield between sections, which reduces hum and increases channel separation.

The 12BH7 can lend a wonderful life to the tone that sounds great for jazz or vocals. For audio listening, this tube can temper the harshness of CD's.
There is, however, a wider variation in the sound of 12BH7s than 6CG7s, so some tube selection or rolling is in order.
You can find very neutral 12BH7s (watch for a coming blog comparing them) . If you don't want to modify the circuit and are unhappy with your 12AU7--this is a good choice.

The 12AU7 family has the widest variety of tonal characteristics which is probably why this tube is rolled so often by audiophiles.
Personally I find some 12AU7s a little tinny in comparison with the 12BH7 and 6CG7, but there are exceptions,such as RCA clear tops and 5963 tubes!

Part of the fun and magic of tubes is rolling them when listening to different types of music.
