Hello Peter: Yes, I'm still in contact with amateurs that are still using
the RF-110 (AM-3924) and variations. The weak link for amateurs is the 19
band switching output network. It works fine at 1 kW output, but most
amateurs want to use the power available from the pair of 4CX1500B's to run
much more RF output. The tank switch and tune/load fixed capacitors are
pretty much at their limit at 1 kW and can get unhappy at higher power. The
tank is broadband, 2 mHz wide per band at the higher frequencies and can and
should be returned for much better efficiency inside a narrower ham band.
The two 8122's and two 4CX1500B's are often worth more than what a lot of
folks pay for the amps surplus. Good luck with your project. Let me know
how you make out. I have a lot of fond, and some less than fond, memories
on that long and successful product line for Harris/RF.
