Has anyone done this? I'd like to be able to adjust the bias in my 2:90 so I can try different tubes.
It looks like 2 of the tubes running at the -57 bias voltage are the ones I want to play around with since they are the Class AB pair while the other two are the class A power tubes with cathode bias. That make sense?
