[Jukebox-list] Rockola 418 carriage moves when playing

[Robert Beyer]

Hi I'm new to the list but have manage to keep a Rockola Rhapsody going for some years.  I made one good one from two bad boxes.
  What is happening now I thought was a microswitches/cam problem but apparently not.
  Unit plays fine when first turned on but after warming up , magazine starts to move while record is playing.. loosing its place , after play gripper works but of course is going to try to  put the record in the wrong slot , so if you don't catch it - walla you have a good chance of finding a broken record !
  anybody seen this .  I went back thru the lists files before asking and didn't see anything.
