[Amps] Harris RF110 and RF130 Amplifiers

[Edward Gable]

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.
