    Pioneer PL-420 (PL-5) erratic motor speed

    Hello I found this cool looking turntable at a garage sale but it has some sort of problem with the speed, especially in 33 1/3 rpm mode. It spins erratically: slowing down, pausing, then spinning slightly backwards then forward again. Here's a video showing the problem...
