What am i missing here ?

6N7 has a common catode so you´ll have to have 4 tubes ?

Your schematic shows one tube shared.

With 6SN7 you need 2.

Gost22 means the 6SN7 (= Russian 6H8C = 6N8S)

He states 6N7 as first choice and has copied it into the schematic.

Russian or not the 6N7 is common catode.

Well, the photograph is of a Russian double triode equivalent to the 6SN7.

Yes, yes equivalent!
I would say that this tube/valve 6n8s (military) is better for this kind of thing!
So let's move on ...in the right direction,...

What's the purpose of stealing one of John Broskie's copyrighted schematics to ask the same question you've asked in about a dozen other threads?

I think you just like posting schematics and asking the same questions over and over. Erik's advice (and what others have told you again and again) is correct. Stop posting the same question and build something. Soldering irons aren't poisonous.
