I have to agree with Gary. You're seeing 1600 watts PEP and 400W of carrier
OUT with a pair of GG 813s??? Does not compute! Just curious, are you
talking about 400W INPUT power to the linear under carrier only condx
maybe? If
so, this would work out to about 133W carrier OUT and each 813 dissipating
about 133W which would make more sense.

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.
