Attn. CAM members.....
Beware of fakes when looking for vacuum tubes.
Even the "cheapest" ones are faked / doubled stamped or well-used and sold as new.
I have seen many Russian tubes re-stamped branded
"Made in England" ???????

Buy from a reputable dealer, e.g., CAM members Upscale Audio,Tube Depot, etc.
Try hard not to buy (blind) on ebay unless you have a past reputable seller!
Beside shipping costs are usually padded into the price or too high!

Available matched pairs of:
6N1P-E
6H1N-EB
6N1P-EB
6N1P-EV
6N1P-VI

Made in Russia

6N1P tubes from 1960's is now very rare, and produce most accurate balanced smooth sound, with excellent detail!
The 6N1P (Russian: 6Н1П) is a Russian-made miniature 9-pin medium gain double triode vacuum tube intended for use as a line audio amplifier and cathode driver.
Similar to the 6922 / 6DJ8 tube type is equivalent to the European ECC88 / E88CC tube and can be used in some 6922, 6DJ8 or ECC88 circuits.

Similar to the 6922 / 6DJ8 tube type is equivalent to the European ECC88 / E88CC tube and can be used in any 6922, 6DJ8 or ECC88 circuit.

If you have a good pre amp or phono stage, you need at least gold grade.
The 6N1P (Premium) tube is a very noticeable upgrade over the Sovtek 6922 tube and Electro Harmonix 6922 tube.
They are incredibly durable and can handle the punishment of modern pre-amps, including those made by Audible Illusions.
They excel in detail, speed, and sound stage.
The highs have air and sound natural.
Made in the "Voskhod" factory in Kaluga (USSR)
Ultra low noise tubes and made in Russia.
This premium Russian built NOS 6922 tube replacement is also known by various Russian names
These tubes are of premium quality in both sound and construction.

Basic data:
Uf = 6.3 V, If = 600 mA
µ = 35
Ia = 7.5 mA
S = 4.35 mA/V
Pa = 2.2 W

The 6N1P has similar ratings to the 6DJ8 and in the past was sometimes re-branded as such, however differences between the two types (the 6N1P requires almost twice the filament current and has only one third the S value) mean they are not always directly interchangeable, depends on design of amp/pre amp.
The S is about 4.35 ma/V, the 6DJ8/ECC88 has a S of 12.5 ma/V and a gain of 33 and a lower internal resistance.
However, the 6N1P is typically more linear for a given load.
It is therefore inaccurate to say that these two tubes are identical.
The closest western equivalent to the 6N1P is the well known 6BQ7A.
A ruggedized/extended ratings version of the tube is designated 6N1P-EV (Russian: 6Н1П-ЕВ).
It has currently found a use as a driver tube in hi-fi tube amplifiers (such as Audio Research models VS55 and VS110) because of its excellent low distortion and low noise characteristics.
These tubes were manufactured by the "Voskhod" plant in Kaluga, Russia

6N1P is considered to be the most balanced tube made in its category
and the 6N1P is considered to sound the best out of any of the 6N1P tubes.

6N1P from 1960's is now very rare, this one should produce the same balanced and smooth sound, with detail and alive

These tubes produce the highest quality sound and are considered quite zippy!

Looking for 6N1P-E BOX PLATE tubes from 1960's is now very rare, and produce most accurate balanced smooth sound, with excellent detail!
The 6N1P (Russian: 6Н1П) is a Russian-made miniature 9-pin medium gain double triode vacuum tube intended for use as a line audio amplifier and cathode driver.

Basic data:
Uf = 6.3 V, If = 600 mA
µ = 35
Ia = 7.5 mA
S = 4.35 mA/V
Pa = 2.2 W

Every 6N1P tube should have a pure gold plated filament
The 6N1P has similar ratings to the 6DJ8 and in the past was sometimes re-branded as such, however differences between the two types (the 6N1P requires almost twice the filament current and has only one third the S value) mean they are not directly interchangeable.
The S is about 4.35 ma/V, the 6DJ8/ECC88 has a S of 12.5 ma/V and a gain of 33 and a lower internal resistance.
However, the 6N1P is typically more linear for a given load.
It is therefore inaccurate to say that these two tubes are identical.
The closest western equivalent to the 6N1P is the well known 6BQ7A.
A ruggedized / extended ratings version of the tube is designated 6N1P-EV (Russian: 6Н1П-ЕВ).

They are incredibly durable and can handle the punishment of modern pre-amps
They excel in detail, speed, and sound stage.
The highs are quite airy and sound so natural!
Premium quality in both sound and construction.

6H23 Type 3 - Also called a 6H23P-EB.
This tube is new old stock, and haven't been made since the 1980's.
It's the most durable 6922 types we have.
It is very clear in the mids.
Great extension top and bottom.

Now I know that these Russian tubes were made for their space program - and were used into the '80's where in the west solid state were then being used.
So these had to be built hardier (the glass is thicker on the Russian tubes).
All the particular construction materials and processes just lined up the right way,like great wine vintages.
They are also rated to a higher voltage then the European variants like the CCa, E188CC, E88CC, ECC88:
These have the same construction with a greater amount of getter flashing - and an overall sound signature similar to the regular - just more of it!
Just a tad sweeter, dynamic and a bit more flow factor - the sound staging a bit deeper and wider - more holographic.
Just a bit more of all the traits that had me falling in love with these tubes!

But if you have had trouble with noise or you own a difficult pre amp, this is the tube for you!

If you are having problems with 6922 tubes going noisy or microphonic, look at the specifications for your pre amp.
If it has 25dB of gain or higher, you need to know some things and what your options are.

Platinum grade - The best of the best.
Lowest noise and microphony with the tightest triode balance we have available.
This is typically 10% or tighter

Gold grade - Low noise and microphonics with a triode balance typically between 15% and 20%

Driver/Buffer grade - Lowest noise but not the lowest in microphony.
Triode balance will be similar to Gold grade.
This grade is only suitable for use in the driver stage of an amplifier, or the output/buffer stage of a DAC or CD Player.

If you have a pre amp or phono stage, you need at least Gold grade.
The NOS 6H23P-EB (Premium) tube is a very noticeable upgrade over the Sovtek 6922 tube and Electro Harmonix 6922 tube. They are incredibly durable and can handle the punishment of modern pre-amps, including those made by Audible Illusions. They excel in detail, speed, and sound stage.

6DJ8, 6922, 6N1P etc. compared
Since some time there is a Russian tube on the American and West-European market with the code 6H1Pi that is translated 6N1P. This tube is sometimes called the equivalent for 6DJ8/ECC88 or 6922/E88CC. We find this incorrectly!
Unfortunately will the notion "equivalent" not be interpreted the same by everybody. According to us, must a tube which can be used as equivalent, be at least for 95% have the same parameters as the tube he must replace. And of course 100% pin compatible. So is for instance a 6DJ8 wich is made in the sixties by Philips (in the Netherlands) for an American colleague, exactly the same as their ECC88 sold on the European market. Only the imprint is different.
Of course is the 6N1P pin compatible with 6DJ8, ECC88, 6922, 7308, E88CC etc.. Also the Mu is almost te same, 35 instead of 33.
Unfortunately there are a few parameters differently, such as the mutual conductance, internal resistance and maximum anode voltage. You can see that in the table below. Also the heating current is not the same, it's even 100% more, then the other types. With a large enough power transformer that shall be no problem, but it is something to care about.
Also the characteristics are not the same and therefore the bias point is rather different. That is an important reason wherefore it can not replace in all times a 6DJ8 etc.. Especially on a rather low tension, for intance about 90V (or lower) works the 6N1P not goed or even not at all. On tensions above 150V, if the idle current is correct this tube can give very good results. Especially the High Rel version 6N1P-EV has already astonished many people, because it came in a few circuits to better result then famous brands like Mullard, Philips etc.. And that for about 1/4 of the price! These performances are very dependable of circuit and anode tension.

If you design your own circuits or do modifications on existing equipment, this can be a very interesting tube.
There exist till now no versions with goldpins. The plane 6N1P has the usual dull grey pins, the 6N1P-EV has nickle plated pins, such as the Russian 6922 and 12AX7WA.

*** SAFETY WARNING *** READ THIS FIRST!!!!!
Working inside a tube amplifier can be dangerous if you don't know the basic safety practices for this kind of work. If you aren't prepared to take the time to learn and apply the right precautions to keep yourself safe, don't work on your own amp. You can seriously injure yourself or get yourself killed.
This section is not intended to be a complete guide to safety in tube equipment, just to hit the high points as refresher for those of you who have some experience.
The best way to learn the requirements and practices for safety in tube equipment is to find someone who will teach you one on one.
BASIC REQUIREMENTS
UNPLUG IT FIRST Pretty self explanatory. Do not, ever, ever, leave the equipment plugged in and start work on it unless you specifically intend to make some live-voltage measurement. Leaving it plugged in guarantees that you will have hazardous voltages inside the chassis where you are about to work.
This is like setting a trap for yourself.
LET IT DRAIN If the amp has been turned on recently, the caps will still have some high voltage left in them after the switch is turned off. Let it sit for five minutes after you turn it off.
SUCK IT DRY When you open up an amp, you need to find a way to drain off any residual high voltage.
A handy way to do this is to connect a shorting jumper between the plate of a preamp tube and ground.
This jumper will drain any high voltage to ground through the 50k to 100K plate resistor on the tube.
To do this successfully, you will need to know which pins are the plate pins. Look it up for the amp you're going to be working on.
You'll need to know this for the work anyway.
Leave the jumper in place while you do your work ( high voltage electrolytics caps can "regrow" voltage like a battery sometimes. Really. )
Remember to remove it when you finish your work.
TEST IT Take your multimeter and ground the (-) lead. Probe the high voltage caps and be sure the voltage across them is down, preferably to less than 10V.
BUTTON IT BACK UP FIRST Take the shorting jumper out. Put the chassis back in the cabinet, making sure all of your tools, stray bits of solder, wire, etc. are out of it. You don't have to actually put all the screws and so forth back in if you believe more work might be needed, but make sure that the chassis is sitting stably in the cabinet and won't fall out. At the end of a listening test, either continue buttoning up if you're done, or go back to UNPLUG IT FIRST

Tubes in italic, like this text, are not "direct replacement" types. However they may work in some circuits, and some of them are known to work.
* Note: ECC40 is only electrically equivalent to 6N1P, its socket is different so a direct replacement is impossible.
Find some other references for your tubes here!
Some known problematic tubes to replace:
6N6 (chinese), 6N6P (russian). This tube has NO known direct replacement: the best replacement is another 6N6 - 6N6P. However if you are experienced, and with the proper tools, it could be replaced (given socket rewiring and maybe some circuit tweaks) with 5687, 12BH7, ECC99 or E182CC. This last tube seems to be the closest equivalent.
6N2 - 6N2P: the question here is, can I replace it with ECC83/12AX7? Yes you can, but you HAVE TO REWIRE THE SOCKET. Refer to the tube datasheets for this: as always I suggest to have this work done from experienced people, don't try poking inside dangerous tube amplifiers if you haven't done this before!
6N1: not much info. Best replacement is still another 6N1. ECC88 and its various cousins might work, but be careful of the much higher filament current for the 6N1, and muchlower allowed plate voltage for the ECC88. If the amp runs the 6N1 at less than 130V you can safely replace 6N1 with ECC88 (don't know how it will sound...), but if the quiescent plate voltage is more, ECC88 might fail and ruin your amp. See also here for deeper information.
6N30 - 6N30P - 6N30PI - 6N30PI-DR. Absolutely no western equivalence: the only known source for these is Sovtek that still makes them. However, russian NOS ones are even better but they're becoming scarce and expensive
