Hi Lane,

You can get 4 K out of a pair, but unless you have a BIG 
exciter you'll need to grid drive the tubes.

4-1000A's get a little unstable at 5000 volts and above, especially 
on ten meters, so you may have a little fight on your hands with 
stability. But it probably won't be anything you can't cure.
