Tim (kamakiri) very nicely offered me the opportunity to buy the RCA amplifier from this console. I accepted, I have always liked RCA commercial sound equipment and this amplifier is right up my alley. The noise problem turned out to be a noisy plate load resistor on the first 6N7, and also a noisy 6N7. I didn't have a spare 6N7 but did have a 6A6 (same tube with pre-octal base). I took the base off a rusted through 6SK7 and rigged up the 6A6 to work as per photo... And work it does, the amplifier sounds great and I have been enjoying using it every day. It's not "hi fi", but it sure makes music. See attached image with the ridiculous (and temporary) adapted 6a6.
