And of course they are correct. It is the very textbook DEFINITION
of Class A.

No it's noy. In class A, the devices amplify the entire waveform, all the
positive parts and all the negative parts. The device never cuts off, but
that's not the definition.

Actually, William, what I was trying to explain to these clowns Graham
Stevenson, Arny Krueger and Don Pearce is that "under any signal
condition" totally negates the first part of the definition, that "the
output device(s)never cease conducting".

Many years back, Pioneer came up with a class AB transistor amp in which the
bias was clamped in such a way that the devices never cut off. But that
didn't make the amp class A.

This is a classic example -- common among engineers, and very common in this
group -- of thinking you understand things you have no comprehension of.

It is worse than that with this bunch of self-styled "engineers": they
think that their personal animosities are a licence to redefine
definitions to embarrass their "enemies". In other words, they lie on
professional matters for personal reasons.

What sort of physics is that? It is past time for us to haul up
Stevenson, Krueger and Pearce, and to explain to them sternly that
personalities cannot ever substitute for the principles of physics.

Those three substandard jerks are an embarrassment to decent, honest
engineers everywhere.
