I would tell you to go back to school but I'm afraid that wouldn't

that a SSB voice amplifier operation can be directly compared to a
music audio amplifier operation.

The envelope of an SSB signal is nothing more than pure audio. That's what makes
it so much more efficient than AM -- no overhead from a continuous carrier, and
no redundancy due to an extra sideband. Got a public library nearby? Need a
reference?

I see you are ignoring compression again.

We all no the truth now. Your SSB signal has no compression, therefore
you sound like a mouse. No wonder no one pays any attention to what
you say.

COMPRESSION HAS NOTHING TO DO WITH IT, YOU IMBECILE!!!
No audio = no RF = quiescient power drain! Good God, man, don't you have ANY
reference handy? An ARRL handbook maybe? If you have an SSB amp that is 50%
efficient and you input a single-tone audio sine wave for an output of 100
watts, what's the power input? 200 watts + quiescient power. For an output of
200 watts the input is 400 watts + quiescient power. Are you getting it? Or do I
need to draw you a picture for when you aren't stoned?

Evidently, he's one of those guys who believes in running the
compression up to the point where a mouse fart in the next room will
move the power meter, and average voice peaks disappear into an almost
carrier steady power which rarely drops below 75% of peak......

In that case, the amp will be drawing more power that a capacitor can
make up for.
