6N1 Chinese tube and others

Thought some like to know some info after much painfully researching.

6N1 = 6AQ8 - ECC85 is NOT a 6DJ8 can be converted to 12AU7 by rewiring the heater circuit

6N2 + 6AX7 6AV7 ECC41 can be converted to a 12Ax7 by rewiring the heater circuit

6N11 = 6N1P close to 6DJ8

The Russian 6N1P is not a direct replacement for the Chinese 6N1 it may work in many of the circuits though, but will make it sound quite different. It is closer to the 6DJ8 but draws more current.
 
That link is full of errors, I already know it when I made the article shown on my website (that was the link).

Look closely, ECC85 has a mu of 55, a gm of 6.1ma/V, and a filament current of 435mA. I can't understand what you find close to a tube (6N1 or 6N1P - no difference, one is chinese other is russian) that has mu of 35, gm of 4.55mA/V, and 600mA of heater current. Maybe they're compatible pin-to-pin, but so does 12AX7 and 12AU7 :smash:
 
Ok do you have a real spec sheet on the chinese 6N1 ?
You will fine many on the Chinese 6N11 which is the Russian 6N1P
From what I find on the 6N1 from the Chinese webs sites all point it to the 6AQ8 ?
Also some suggest even using a 6AU7 in it's place
I am surely not saying you are wrong it just seems you can not find a real 6N1 data sheet
If you know where to find one please post a link here :)

You may be right I found these spec sheets though I can not read chinese to well :bawling:

6n1 - http://www.mif.pg.gda.pl/homepages/frank/sheets/095/6/6N1.pdf

6n1p - http://www.mif.pg.gda.pl/homepages/frank/sheets/112/6/6N1P.pdf

A quick search on TDSL brought up this datasheet; the specs seem to be identical to the 6N1P. I think the 6N1 and 6N1P both have been misidentified as 6AQ8 equivalents in the past just because there is no real Euro/US equivalent to this tube: someone flipped through their tube book and picked the first 'close enough' tube that they saw. This very rough approximation gets copied around enough places by people who have never seen a 6N1 or 6N1P (i.e. almost everybody in the west before the 90's) and it begins to seem authoritative...
 
i am glad to share some info:

-these tubes was made in old times,around 50s ~ 70s.beijing & shanghai both have tube factory.they were stopped.shuguang tube factory is still running,they make good tubes(300B,2A3,KT88, ...etc)

-these tubes have quality classification,usually label with a capital letter.
Q is for the research.
T is the best.
J is the better.
M is the good.
通用一 & 通用二 is for radio.
业余 is for study.

-alternate list(the below is the most common stuff i can buy in the market)
6N1=6AQ8,ECC40/82
6N2=ECC41
6N3=6A8Q,2C51,ECC42
6N4=ECC83,12A×7
6N5P=6AS7,6NS7G/GT
6N8P=*6H8C*6H8M,6SN7
6N11=6H23П,6DJ8,ECC84,E88CC,6922,CV2492
6J1=6AK5
5Z3P=5×4G,5U4G
5Z4P=5Z4G/GT
6Z4=6×4
6n11,6n8p,6n3,6j1,5z4p is my favor.

The small Chinese tubes are about 4 times the price of equivalent Russian tubes on Ebay and other internet stores, when you can find them. In my limited experience I have found the halves of twin triodes to not be well balanced. I have found leaking cathode to heater on a few valves 6P1. Sound is good but quality is questionable and four times the price of Russian equivalent type. It's a no brainer, unless the prices drop and lets find the gems in there. Yet Tubesteve says they go for USD$1 in China.

Sorry for diggin' up an old topic, but i'm quite sure that 6Z4/6Ц4П has different pinout compare to 6X4, although they have similar rating.

I fully agree on that point. As far as basic tube parameters are concerned,the closest equivalent to the 6N1 would be the 6BQ7 (or 6BK7) but you'll also need to check and compare the maximum ratings. The ECC85/6AQ8 is a poor substitute,as well as the ECC40 (with a different basing!). The fact is that despite the (often contradictory) informations available here and there,there are no real equivalents to these chinese tubes. Substitutions may (or may not) work in your circuit. (=application dependant).

Sorry to take your time, but are you saying that the pinout is the same as well? (6n3)

Thanks,
Nick
