As I recall Henry Radio rated one of their "pair of 3-500" amplifiers at
3000KW input, at 60% eff. (not unlikely) that would be 1800 watts PEP
output.....NO?

Well, my SB-1000 with ONE 3-500z will produce 1100 watts output, if I
forget to turn down
the drive from my exciter.
The question is "for how long will it do this?" My guess is "not too long!"
