The figures are about right, half the rated dissipation is about what
carrier level should be.
I used to run a pair of 813's in parallel, zero bias GG on AM.
240W dissipation and the tubes ran with color allright!
360 W out
260W dissipation (brighter color)
something was never quite righ with the efficiency in that amplifier, but
it was running close to the max. frequency for the 813 and they are not too
A big fan on the bulb works wonders for the 813.
