…After some additional analysis, there seems to be a heat/time component.
When the player has been switched on and playing “for a while” the high pitched noise goes away playing those end of disc tracks.
I also lifted the player and gently angled it in different tilts, that did not lessen, change or remove the squealing.
so something heats up and expands? or something heats up and becomes less viscous?
Thanks!
