Your 6V6GTs will make good output stages for modest power ~ 10watt in push-pull. A lot of guitar pratice amps use those.

The 6AU6 is a sharp cut-off RF pentode that is suitable for audio use. It can be used as a normal voltage amplifier in pentode mode, in triode mode with g2 and g3 strapped to plate, or in triode mode using g2 as anode and with g3 and plate grounded (small signals only). The 6AU6 is also good as a constant current source/sink,

I've seen the EF50 used as the input tube in a SHT SE amp. It was on Tossie's Japanese sit, I think.
I have about a dozen of them myself.
Does anyone know where I can get some sockets for them? It's a 9 (nine) pin loctal.
Peace,
DrRick
