Kenwood TL-922A Legal Limit - Trade???: I have a robust Kenwood amp I have had for several years. I bought from the original owner. I just updated power supply capacitors, diodes, and bleeding resistors with the Harbach kit. Works great as you can see from the picture it is producing 3500 volts. Eimac 3-500Z's that can handle 120 watts input that should put you at legal limit. These amps were built like a tank. I'm looking to trade for a transistor type amp, Mercury, Ameritron, Acom, etc. Tell me what you have. Would have to trade on site no shipping. Email first then exchange phone numbers.

JUMA PA100: I have a rare Juma amp in mint condition. Absolutely pristine.The size of the JUMA PA100 is compact and it is equipped with a fan in the heatsink. The fan is typically OFF during normal QSOs and it starts only when needed. The fan is very quiet. Great to get a boost when band conditions are marginal.
The Tokyo Hy-power hl-100bx and hl-200bx are comparable except this amp is very much smaller and compact. Great for camping, portable, travelling, SOTA, etc.

The JUMA PA100 amplifier can be used with any low power transceiver or transmitter with output power range of 2.5W...10W gives 100w!!!

FS - Kenwood TL-922A HF Linear Amplifier: I have for sale a Kenwood TL-922A Amplifier. I would rate it in good condition. The front panel is very nice but there are a couple of scratches on the top of the case. This amplifier is from an estate so I do not have a history with it but I have tested it and it works on 160-15 M. It has not been modified to operate on 10M but the there is a Kenwood modification to enable operation on 10 M. There are YouTube videos available too if you want to see how challenging the task would be. It has Eimac 3-500’s with 1978 date codes that I would assume are original. On 160-20M it puts out between 1150 and 1300 watts. On 15 it was 950 watts and I had to run the tuner in the exciter because the input swr was high so the tuned input must need something. It is currently set up for 110V operation. I’m asking $1050 for the amplifier. I really don’t want to ship it. My preference would be for the new owner to pick It up and try it out.
