sounds good, Wing C EL34 paired up with a Raytheon 6CA7 from Japan , was there a Mullard factory over there?
got a 12K resistor feeding the PI with no filter cap, don't know why, gonna leave it that way, dis-similar input caps on the power tubes, gonna leave it, 1/4th cathode bias, 3/4 fixed,
i see an error in the output section, can anybody spot it? 10 pts EC.

Missing grid stoppers?
no, but that is a good point! the error is in the power tubes,

What's wrong there?
EL34's need external connection,
the 75 ohm cathode resistor kind of makes up for the lack of a tube rectifier,

Impressive beverage count, CJ. I'd love to see at least 3, though. 8)
