Jim, more years ago than I can remember I built a 4-1000A GG amp.? It was ok, but hard to drive. At that time I had a HT-37.? I came upon a
3-1000Z, which can be plugged right into that same socket.? With 75 watts from the HT-37 I could drive the 3-1000Z WAY beyond legal limit on 80 meters, and it performed well up through 10 meters.? It was stable and a very nice amp.? I still wish I had not sold it.
73,
Mike, W5UC
The 4-1000A is a pain in the rear end and Im getting to old
to struggle with them.
