I'm not sure you can get more than around 1kW PEP output of a pair of
813's... and probably more like 800w. (3) in parallel would be a
different story, though.

I would say you are pretty much on the mark there. I have a pair of
813's in GG also. I only run them at around 2500 volt and can get
about 650 watts max out with 100 watts drive if I remember right.
I ran them well over 3000 volts many years ago and got quite a bit
more out of them but didn't have a decent watt meter then so I don't
know exactly.
1000 watts out seems doable but they will be running around 1600 watts
or more input. They will turn pretty red. Even on SSB at that power.
*whew* We agree on -something- ;-)
But I'm enjoying the discussion. I may not be the most articulate
individual around, and I'm -far- from reminding anyone of someone whom
posses articulatino, but when it comes to someone saying "375w is the
limit to run to get 1500w pep output", I can't swallow that. It's a
true statement, if you were to apply a sine-wave (at an arbitrary
rate... say, 1kc) to 100%, but as it's been said before, we don't -talk-
in sine-waves.

But it is also true for voice modulation if you are talking about
modulation peaks at 100% positive. Modulation is modulation.
