And it may not really even BE a true mu stage driver, but anyway....My question is about the cathode of the lower triode in the so-called mu stage. Should that bypass capacitor be ever so small(.01ufd)?
Could replace both the resistor and the capacitor with a AA NiCad as I doubt the input will ever exceed 2V PP, but I'd like to try this schematic as I already have the Grid Chokes and most of the film capacitors required.
