H Pioneer SX-770 Vintage Receiver In Excellent serviced Condition. Early solid state model from Pioneer that was one of their first models to put them on the map stateside as a major hifi brand. This is from the collection of a professional audio and electronics restorer with biography below:

I've collected and restored about 750 "collector electronics" made from the 1950's through the 1980's as my hobby over 20 years, including receivers, amps, pre-amps, turntables, cassette decks, speakers, reel-to-reel tape decks, professional disc jockey equipment, transistor radios, ham equipment, citizens band equipment, etc. my wife recently has threatened to throw me out unless I begin to find a loving home for these electronics which have been stored in a heated and air conditioned facility. I've taken off every knob, replaced defective tubes, transistors, resistors, capacitors, diodes, coils, etc. in these restored and beautiful electronics.
