Hello Jim.
just wondering if you can help me a little regarding of the KT90's .
I got an amp running EL34 PP triode connected.OPT is Tamura F2020 (3.5K PP) rated 50w . my amp at the moment run roughly 400v on the plates and cathode bias I'm not sure how many MA per EL34 but the cathode resistor is 470ohm and I have around -29v ( 29v)
if I want to droop in the KT90s what do you think ? and what bias resistor I have to change to?
note : the amp is long tail pair of 6SN7s phase invertor . and 6SN7 input as well.
hope you can help
Cheers
