This is a Swan 117-XC power supply. It produces about 850 vdc for the final amp plate supply, 300 vdc for the hv needed by most of the radio tubes, -100vdc bias, 12 vac for the tube filaments, and has an external speaker & headphone jack. It was in pretty good electrical condition, but needed cosmetic help. I recapped the supply (forgot to take pics), reapplied the wrinkle finish, and compounded the faceplate. The speaker grill was a low grade of stainless that rusted. I tried everything, but couldn't get the surface rust out of the perforations...making it have a overall rusty look. I finally sprayed it with a paint color called "stainless steel", and it turned out pretty good. This supply runs many of the Swan rigs from the 1960's.
