My pair of 813's will do 600 watts carrier all day long, 700+ is no problem, they are supposed to run 2000 volts at 400 ma (a pair) but you can increase the voltage or current with some forced air cooling and icas service.
A pair of 811a's is not enough, and I don't know about running them at 2000 volts, they will take it I guess, I have run them at 1750 volts, but a pair of 4x150a/4cx250b in AB1 does real nice, 900 watts of audio out at 2000 volts. For lots of clean iron, tubes and sockets, the price seems reasonable. I sold a pair of 812A's modulated by 811A's I built for $2000.00. That was good for about 350 watts of carrier, no exciter. A pair of 813's is a good start!
