Thanks for the replies. I, too, at first thought it would involve a
padder
in the output tank circuit. Something I should have out in my first post:
there are no padders in the output circuit. The schematic I have shows an
output circuit that is a Pi network (the inductance is an air core coil
in
series with a toroid inductor) into a toroid transformer (I am guessing
it
transforms about 200 ohms down to 50 ohms).
#### Yes, All the Command tech HF amps and even the 6 meter ones have a 200
ohm Pi net followed by a 4 to 1 transformer. This eliminates all the
switching and padding of both load and tune. It does work, but it is not a
design used by most amp Mfgers.
