Unfortunately, it makes a terrible mess of any modulation
-------------------------

Reg,

Well not ANY modulation, just signals with amplitude modulation components.
But this is a well-known property of Class C amplifiers, so what's the
point?. If we want to talk about Class B or Class A, we should start a new
thread.

The 'power dissipation' in a Cass C stage is primarily a function of
what
percentage of the cycle the stage is neither in saturation nor
cutoff. A
perfectly rectangular output switching waveform of any duty cycle ,
if it
could be achieved, would result in nearly 100% efficiency.

Unfortunately, it makes a terrible mess of any modulation.

To avoid distortion and non-linearity, saturation can be permitted
only on the extreme peaks of the modulated driving waveform. Class-C
is ruled out. Class-B or Class-AB prevails.
