I am guessing that this amp was found not operating. Not necessarily not operable.
So, any documentation of any kind available?
Obviously I am new to this forum. I've worked on electronics as a hobby for 40 years and I'm mainly an audio guy. I've always been interested in ham radios and the RF side of electronics. I've recently acquired a Special Products Design Corp. SPD 1000l RF amplifier. It is a massive beast at 100 lbs. It was made for the Air Force in the early 70s, possibly for the Mars Mariner 9 project. It has two 3B28 half wave gas rectifier tubes and three 0B2WA voltage regulator tubes. It works on frequencies from 2.2 to 28mhz. I've looked it over really good and everything looks okay. There are some electrolytic capacitors that should be changed. I'd like to test it to power on, possibly with a variac, but want to know what to expect. I know that voltages could be thousands of volts, and I know safety as far as that goes. Any tips on how to proceed would be greatly appreciated. I would like to get more into radios, but this is much more than I need. I am selling it, but want to test it first.
Thanks!
