A friend did an upgrade on his 220 with an outboard power supply, better
fans, etc... It was a killer amp at 1500W out, all day key down, and he
used it for several years very effectively before going to a bigger amp..
I remember my 220 of some 20 or more years ago as having poor input circuitry...
Nah, just a lousy input circuit SWR, which I need to attack one of these
days.. I know I could get more out at higher plate voltage, but then other
things in the design start to go.
