*Audio Tube Amp Fans:
Please READ....
There is no way anyone else can tell you how any given tube will sound in your amp/pre amps!
There are too many subjective variables for anyone to tell you, unless they have your same equipment and your ears.
You need to try different tube types + variants to see which sound best to you!

*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

Also have many 5963 tubes (12AU7 variants) from $30.00 each
Made-in the-USA RCA / GE 5963 12AU7 Variant mostly short plate tubes in very good condition.

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 we have these 12AT7 RCA Black Plate tubes are designed to be used as an amplifier or it can be combined as an oscillator and mixer

(as long as the frequencies are below 300MHz.)

The RCA brand are the higher quality tubes.

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!

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! ...



All sales final
No exchange/No returns
