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-

Dumb Question: Is the (almost) new belt sourced from VPI?
If the belt isn't to VPI specs, it could affect speed.
Since the motor is housed in a separate box and movable, try moving it in or out a little until you find the correct position. Don't know if that will help, but it's worth a try.
Thanks gentleman. The belt came from Musicdirect with a receipt
that SAYS it's the correct belt, but I guess I cannot totally
rule that out as a mistake.

As far as motor positioning, I have moved it as far and
as close to the plinth as possible, with no results.

Again, thanks for your thoughts thus far!!!
Did you try putting the belt in a bag with some talcum powder? Shake it up a bit, put it on the pulley and table , then see. This may help slow it down.

Though I'm guessing the obvious answer, a VPI SDS, is out of the question?
I own a Scout, and I am not using an SDS, but I'm not having any speed issues either.
I did try the talcum powder trick. No dice. It seems unlikely that it would affect the speed that drastically however. 34.6 is pretty fast.
