VPI Scout running FAST...help?

Ladies and Gentlemen-

For your consideration, I present my very first world but very real audio problem.

Proud (sorta) second owner of a VPI Scout One. 11.5 Acrylic platter, 600rpm motor. Approx 3 years old, appears very little previous use.

At the present, the table is running at a steady and consistant speed of 34.6 and 47.1. I have tested the speeds using my ears (songs sound too fast), a strobe, the old fashioned counting RPM's over a 3 minute period, and even so far as to have a friend bring over a centerfuge calibrator from a medical lab. So I am certain that these are the speeds it is presently running.

Things I think I have ruled out:

Belt is new, but not brand new

Table is on a flat, level surface

Pulley is attached soundly in the motor

The reported speeds are at the top "rung" of the pulleys, I am aware that the higher up the pulley the belt is, the slower the platter turns.

Outlet power is ok, I have tested the table on multiple outlets and it is the same, also, my older Pro-ject table ran a consistant 33.5 on the very same outlet.

This is where I run out of ideas. I have placed an e-mail and call to VPI, but have not heard back yet. Anyone have any ideas? Goin crazy here...

Thanks in advance-
