"...What do you recommend as a good HIGH power amp?"
**********************************
"Roll y'er own!" I say...
The venerable, tried & true 813 is still available both new, surplus, at
Hamfests, etc. Two of these in parallel grounded-grid will give you
600-watts output, four will up the ante to 1.2-kilowatts.
They're practically "free", too, compared to the prices of modern 3-500Zs,
8877s, etc.
And don't let their high internal output capacitance scare you: there are
ways to make them play just as efficiently on 10-meters, as they do on 160.
