Well, you're objecting rather strongly to an assertion that I never made.
In theory if you want to get the maximum available power out of a generator
you _do_ match it's output impedance. In practice if you do this with most
RF final amplifiers you will reduce your final element (whether transistor
or tube) to slag -- that's why modern commercial radios have SWR protection
circuitry.
Please see my reply to your post starting with "Hi Leon" for a full
explanation, and please actually read it before replying. Remember also
that everything I say (including the attempt to match output impedances with
the wall socket -- I was only 8 but that's no excuse) has been backed up by
experament.
Okay, so if I understand you correctly you're saying that whilst you
should try to match impedances in Class A; it's inapplicable in Class
C? It's just an operation class distinction?
