If we are talking a linear amp here then 6KV @1.0 A is pushing it a little
on a single 4-1000A wouldn't you say?

6 KW input at 60% efficiency should give around 3600 watts out. 6000 watts -
3600 watts leaves 2400 watts plate dissipation. Can it be done, I suppose
but kind of tuff on the tube and I will be IM is not so great either.
