hey-Hey!!!,
An amp with maximum output happening with one phase of its PP set cut
off is *NOT* class A. A real class A amp has both phases conducting at
maximum power, and not from some variable pitch grid winding, remote
cut-off stuff either.

Is there actually a power tube with a variable pitch grid winding
designed to do this? I never heard about it before, inquiring minds
want to know more.

Hi John,
I don't know of any either, but given the definition of Class A, I
thought it wise to rule out the remote cut-off behaviour that *COULD*
provide a loophole to somebody fixed on disagreement, yes?
