Oh yes I understood what you meant, I was just hoping Roscoe would chime in as to whether he agreed with your analysis. Makes perfect sense to me but I am no expert on these things (which is why I come here!). But it sounds like you have it on good authority and evidence, so that should be good enough for me.
Out of curiosity, do you think there's a sonic advantage to regulating everything (B+, G2, bias)?
In a single ended Class A amp, shunt reg/current source, probably yes. PP Class AB, I think other circuit issues will swamp any differences there. But please, try. It may be worth the effort.
I do know that a separate supply (transformer, rectifier, etc.) for the input stages, leaving the output section its own supply is a definite and very worthwhile improvement.
