Just an idea I sketched during a coffee break. Comments invited.
Why does Joan Jett look like Freddie Mercury doing a Joan Jett impersonation?
"If you have to use tubes, its better to go passive into a non inverting high Z amp."
Agreed.You made a point earlier about driving the feedback resistor directly from the plate. That could be done, but since the plate resistance of the pentode is very high, any additional shunting of it it would reduce the open-loop gain--which we want to be as high as possible.
