6N1 Chinese tube and others

[redbullet]

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's nice link but he is showing the 6N1 as a Russian 6N1P which many seem to do.
But if you look at the tube info you'll see it much closer to the 6AQ8

Here's a link to a chinese page

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

6N1P was developed as a small replacement for 6SN7, 6N2P was developed as a small replacement for a 6SL7.

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 :-)

Again Wavebourn is talking about 6N1P not the 6N1 which seems to be different tubes.
We need a Chinese or Hong Hong user to chime in here !

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

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...

Also, 6DJ8 is more close to 6N23P, but not to 6N1P.
