Hi Bry, Pair of 813's at 1KW wouldn't be my first choice, but then again for amateur service, give it a try. I don't know........never built one. A pair of 4-250A's X 810's would be a fine first choice, or 4-400A's X 810's to really loaf along.
Trying to 100% plate modulate a pair of 813's with a pair of 811's as modulators at 750 watts DC input to the finals? But,I'd consider looking at the toob specs as not to p*ss beat them, heard the other day some toobs aren't being made anymore. Then again, haven't looked under the hood of the transmitter in question and haven't a clue as to the modulation method. But back to the Sweet Home/Salem homebrew transmitter........still worth a lookie-see. And I don't have a nickel in it.
