Hi, I recently bought a PL-400 cheaply with the speed running slow. I fixed the speed by replacing the trimpots on the motor control circuit board. It seems to be working fine now. I had some questions about the behavior though. When the turntable stops, is the platter supposed to freespin until it eventually stops or is there some kind of braking mechanism to stop the platter quickly? The other question is, should the dots on the strobe be perfectly stationary or is some amount of wobble expected? The music sounds fine to me but the dots wobble back and forth slightly. Video here to demonstrate what I mean. Thanks in advance!
