Your previous explanation was great. thanks!
As far as input signal changing the bias, before I bought the Cary I had a pair of ARCs & they just had me spooked. For example, it wasn't uncommon for a grid resistor to go "POP!" shortly after I hit the power switch. I used to cross my fingers whenever I turned them on. & yes, I did notice that turning on the preamp made the bias do crazy things.I didn't see that in the Cary. It never seemed to matter what I did with the preamp, the bias always stayed put.
