Oh, thank you, Paul. Remind me to invite you to explain something one

People are using 'linear' in two different senses.
No kidding? Only two? ;-)
For audio, in fact
for any amplifying stage with an **untuned load**, linearity requires
linearity of output current with respect to input voltage, (Class A
single ended or push-pull, Class B push-pull).
But with a **tuned load**, 'linearity' can be achieved even with Class C
biasing. This is why linearity in this case is defined as output power
being proportional to input power.
Okay. I'm quite happy with that. Any not?
