TMC PAL-500 HF Linear Amplifier 2-32 MHz RFE-1 RF Deck Only. Uses 2 4CX-350Bs
This is the RFE-1 RF deck from a TMC PAL-500 HF amplifier that covers 2-32 MH continuously giving 500 Watts PEP output with only 100 MilliWatts to drive it to full power. You will have to provide a power supply that produces 2000 VDC and -150 VDC bias voltage. RF amps are a pair of 6CL6s into a pair of 6146s into a pair of 4CX350A beam power tubes. In case you are not familiar with the RFE-1 and PSP-500 that make up the PAL-500, this amplifier was way over-designed and beautifully constructed by TMC in Ottawa, Ontario Canada. It was originally used on the DEW Line defence system in the 1960s into the 1970s and after that at some Canadian airports. A beautiful copy of the technical manual can be downloaded free of charge from the BAMA site and there is a PAL-500 conversion Web page that is also very easily found. Power requirements are 2000VDC and -150 VDC bias voltage. Offered as-is for parts or repair but I understand this was working equipment when it was removed from service.
