Make sure the bearing is perfectly vertical in the plinth. If it has become loose or somehow angled there could be a small tilt allowing the edge of the turntable to touch. This would be seen as the touching always in the same spot on the plinth. If the platter is damaged in its bearing attachment the contact could rotate around the plinth with the same spot of the platter being low and in contact or dragging.
Turntable issue
Hoping to draw from the collective knowledge of Audiogon... I bought a Pro-Ject RPM10 and before it shipped to me it was working fine. When I received it, the platter drags on the bottom. This turntable has a "magnetic lift" to reduce the weight of the platter on the bearings. This doesn't seem to work (demagnetized?). Anyone seen anything like this before and can it be fixed?
