RE: See ...."You're neglecting the behavior of capacitors"

That's a very interesting post and makes perfect sense. But why do I and others who use such amplifiers find that increasing the capacitance of the output stage power supply results in a better more robust bass response, in the context of a circlotron OTL? Granted that the collective Rp of the tubes in an OTL is and has to be much much lower than that of the output tubes in a typical transformer-coupled tube amp. This will somewhat mitigate JLHs dilemma but not entirely. Also, in a circlotron the filter caps are in parallel with the output, I believe. (Can't say I truly understand the circlotron.) Also, shouldn't we be worried about Z at 120Hz, rather than 20Hz or 20kHz? What's flowing into the capacitor would be mostly ripple or DC; yes? Or no?
