Kudo's to you!
I'm just running 100 watts into a 5 element beam, we can use 120 watts pep....though most use more power here as dx station, i limit myself to the 110 watt the transciever puts out.
If i ever needed such amp you would be the place to ask for....
HF is covered, Heathkit SB-1000 i overhauled, new 3-500ZG so that will last me a long time.
Great job on your amps, it shows the dedication put in, and the excellent thinking behind it.
Cheers,
Cor
