Trying to find info on antique GE hifi setup

I inherited an old hifi system which I think is from the late 50s or early 60s. It's an all-in-one cabinet General Electric turntable plus radio which uses vacuum tubes. A sticker on the back says "RC 7130 A" in huge letters, and below, "Made Under G.E. Stereo Multiplex." The turntable plays 33s, 45s, but also 78s and 16 1/2s. The thing is a monster size-wise, and I have no idea if I should throw it out, try to sell it, or see if anyone on the planet could get it in good working order (the am/fm radio was functional last time I checked, and I suspect the turntable needs a belt). Anybody know anything about this unit?
