Excellent video ! I learned a lot and feel much better now in using the 6H8C tubes in my build.

Great to hear!

I have been using these Russian tubes for the last couple years. They really are good tubes!

my favorite 6SN7 TUBE

[@GasPipeJimmy]

Is that writing on the Russian tube in Cyrillic or Latin characters?
I suspect it’s all in Russian.
If so then it’s actually: 6N8S and not really 6H8C
That might or might not help in searching for more.

I have been cheking the 6N8p datasheet and my conclusion Is the Chinese equivalent for 6H8c

[@yuriivanov12]

Yeah, you're right. Every Russian tube has Cyrillic caracters.

[@WildChinoise]

Informative and instructive!

This video has absolutely no value for anyone but your own ego !

[@YoungAhn]

Thank you for watching my videos. I don't believe in audio myth at all. Only scientific/ objective result is my goal, good day sir. Young

Russia tubes are not NOS.
