I have to apologize. The two phono stagas I mentioned, the BMC MCCI, and the 47 labs, are both current driven phono stages, which is an entirely different subject, but I do have interest in that mode of operation for low output moving coil cartridges. However I don’t think either of those is LCR type.
So I guessed correctly, that the 6F12P is in fact a Russian tube designation with Cyrillic converted into English.
