I purchased this unit at an estate sale and am selling it AS IS - FOR REPAIR. It powered on when I found it, but one of the screws holding the RCA plug connector had come loose inside, so I opened the unit and screwed it back in. When I put it back together, POWER DID NOT COME BACK ON. This is the end of my expertise, so I am selling it AS IS - should be fixable for someone with electronics engineering skill, but I'm not certain. May be as simple as a re-solder or fixing a cable, may need a bit more work. This is is a very cool vintage piece, with several 90s wacky morning DJ style sounds. Perfect for messing around with!
