Working on a Wurlitzer OMT that had a bad CD player. I repaired the CD player and here in the shop when testing it, the turntable would sometimes turn faster than the CD and make some noise. Sometimes it would spin and play, but way too often it ends up putting the CD back and not playing it. I had thought that maybe my Rowe/AMI test juke was somehow different in the clamp arm, with less weight or something?
I installed it back into the OMT and it's still spinning/slipping/putting CDs back. The round plastic pressure disc part of the clamp arm is just plastic, no metal and/or magnet. I *think* there was a magnet on the CD player that may have pulled the pressure disc, IF it had any metal in it. To add to the dilemma, the centering cone on the player was missing and I could not find it in the machine. I did install one but am not sure if that has to do with the problem. It doesn't appear to be. So should the pressure disc have a metal washer of sorts in it instead of a magnet?
