I'm with Dennis and Gary. To run a linear amplifier at 375 watts of
carrier and 100% modulation, you will need around 800 watts of plate
dissipation. For a short time a number of years ago, I tried running an
AF-68 and a 4-1000A linear amplifier. I could never get more than around
450 watts of carrier and stay linear............I didn't need a heater
in the shack either.

Darrell, do you still have the powersupply for the AF-68? I have
one here, that I got from Larry/CFJ a couple of years ago, and
I've been wanting to put that thing mobile for so long, that I'm
about ready to build an AC-input power supply, and plug it into
my 600w DC-AC inverter.
Thanks.
