Class C conduction angles are too low to produce reasonable output distortion levels in R.F. linear service.

Some amp builder's smoke and mirrors include suggestion that they have some kind of new technology. They Don't.

Shifting conduction angle during the R.F. cycle isn't a viable technique when linearity is concerned.

You can't fight physics. The rules have not changed since the 1930s.

Even class B amplifiers need degenerative feedback to become good R.F. amplifiers.

You want to see a meter swing higher, use class C and plenty of drive. Some operators are all about watching a wattmeter when they transmit.

You want audio that doesn't sound like you are talking through a kazoo, use class AB or B. There will of course be a lot more device heat to deal with.
