No magnets were next to the player. The coil and distributor were probably four or five inches away behind the cover. I've checked the HD and it seems OK.

I would suggest that dglidden might try a different car or perhaps moving the player temporarily to determine if its getting interference. Maybe a line noise suppresser would help.

All I know is when I move the player away from the motor/distributor it worked fine and has been working fine ever since.
