Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: The best way to use feedback

I don't disagree that NFB causes more problems than is solves but if you didn't triode connect the beam power tubes and the pentodes in the amps that you disconnected the fb then you missed the boat. Without voltage NFB the plate resistance of beam power tubes (and the pentodes) is way too high for the output transformer impedance. But then you never understood much about proper load impedance to start with. You're such a rookie.
