Well... I see uncle Frank is back and lookin' for a fight... LOL
Go ahead and rant & rave, you'll not get one from me. I can't help it
if you're "electronically challenged".

Speaking of the retarded, here's a blast from the past:
=====================
Prof, you are full of it to your earlobes. Rather than go thru it all
again, there is NO, repeat NO way any amp drawing on less than half a
cycle
is linear. It may be linear enough when what is really being run is a
******* Class B which is exactly what you are doing. In this case you
may
expect Class B efficiency with Class B heat.
You are playing semantic games with yourself and us in the process.
Yes, in
a semantic sense Class C is 179 degrees. To anyone with any sense it
is
about 120-140 degrees with examples down to 60. They are largely
self-biased via a grid-leak with only protective bias applied if
needed by
any direct means. Your use of the 0.7volt forward barrier of a
bi-polar
transistor is dictionary Class C only; no tech manual would bother
with it
because, as Young Frankenstein put it, it's doodoo. It is simply
slightly
overbiased Class B.
Your belief in the flywheel or flyback effect of a tank is right up
there
with Linus and the Great Pumpkin. It doesn't happen that way.
Putting a
100 hz tone on a carrier and feeding it thru a proper Class C amp
would
result in the modulation keying the amp and producing a sound like an
infuriated electric razor. Linear my pretty pink tushie.
Now you will more than likely tell me about AM transmitters using
Class C
finals and you would be correct. What you forget is that the
modulation is
APPLIED to the final, not contained in the driving signal. The finals
do
not amplify a modulated signal because they can't. Because FM uses
steady
levels, linearity is not an issue.
If you paid some attention to matching and levels in the tank you are
one up
on most of the bozos building amps down at the local bodyshop. But if
they
got the same level of technical understanding I see here so far, I
have to
seriously question whether any such amp exists.

Hardly... A class C amp can faithfully reproduce the input signal by
having
a high "Q" tuned tank in the output. It's done all the time! That is the
true meaning of linear.
A 'Class C linear' is an oxymoron.
