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.
