VPI vacuum too much??

Does the whole platter/motor stop turning, or does the record stay stationary while the platter beneath continues to turn?

Mine does the latter unless the clamp nut is tightened very securely. Check to may sure your clamp is tight whenever this happens. If your problem is the former, it sounds like your motor may have some problems.

Make sure the plastic screw on clamp is pretty tight against the record.

It may be the mat is spinning underneath the LP.

Tighten the plastic clamp.

Checked it today....tightened the cap more, and no problem...thanks....
