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-

I bet its the motor. I also bet VPI doesnt call you back anytime soon. Sorry, guys, but I am a VPI owner and I just cant get an email back from those guys. I know they are only in on the days that the moon is alignied with Io, but still...

I did get an awesome upgrade by going from the motor you have to the upgraded one, and, for a grand, maybe the way to go-you should also add the SDS (another grand).

Thanks all for the replies, much appreciated. I did forward this thread to VPI and got a response from Ian, who had me send some pictures, but then the line of communication went silent again. Bummer. I may consider the upgrade to the 300 rpm motor at some point, seems pretty basic and not all that expensive. I'll try and keep you all posted if/when this gets resolved.

Hey guys-

Got ahold of Matt at VPI today, and I just need to send out the 12" pulley and they will send one back for the 11.5" platter...any tips on how to take off the pulley? Is it a tiny little hex nut on the bottom of the pulley itself? The rest of the Scout uses a 5/64 hex, this one seems smaller? Thanks in advance!!!

The pulley has a small allen key grub screw. Just back off the grub screw and the old pulley will slide off.
