Default Why are "engineers" so poorly educated?

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.

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.
