[Elecraft] KAT500 and SB 200 Amp

[Ron D'Eau Claire]

I was Mike. The SB200 is rated at a maximum power of 1200 watts PEP sideband
and 1000 watts CW. But that is DC *input* to the final amplifier tubes. That
was how transmitters were commonly spec'd back then. 

In use the SB200 runs about 500 to 600 watts RF output, which is fine for
the KAT500 as you note from the specs.
