Too damn sick to go out to shop today, stayed in the basement and worked on some old Sun Electric equipment. Figured it might make an interesting tech article if someone was curious about how to fix some old electronic gear dating back to classical antiquity... Its an old Coil Condenser Tester from Sun Electric built in 1966. The only reason I know the date is because Sun seemed to unambiguously stamp a build date on the back side of the case of everything they built. I picked it up at a swap meet a few years ago for a few bucks not knowing what it was or if it worked but figured it was cool enough to find that out later. Sun made a ton of cool gear like this and I figured with a condenser tester with cathode ray tube (CRT) and analog meter would be cool enough just for parts for other projects if it was a total failure.
