Tube Cross Reference Matrix?

[bluepearl]

I recently acquired a very nice tube preamp made by Tube Magic Canada. The core of the beast is made in China and it utilizes three types of Chinese (Russian) tubes. I am looking to replace the tubes with either Russian NOS or preferably NOS NA tubes (RCA or other). I've been searching the net looking for a cross reference table that will show me all the options available. Can anyone send me a link?

From the research I've done so far these are my options (so long as their correct...)

Current - Option
6C19 - 6S19p or 6S19p-v
6F2 - ECF82/6U8/6GH8A
6N6 - 12BH7

Is anyone familiar with these tubes and the tube options?

there's this one - http://hktubeaudio.homestead.com/files/tubecode.html

I had a link to another such list, but it seems to be dead now... should have saved a copy!

Replacing the 6N6 with a 12BH7 is likely not needed or advisable. Different pinout and heater requirements. Buy a set or two for spares of Russian 6N6 (from good dealers in Ukraine). I don’t have experience with Chinese 6N6, but the Russian made 6N6 tube is a good-sounding device.

I have used NOS ECF82 in a circuit designed for Chinese 6F2 tubes and had good results (never actually tried the 6F2 though).
