VPI Scout - slow speed , help ?

Hi

I've recently purchased a KAB speed strobe which has indicated that my Scout is running very slow (notches moving counter clockwise); over 100 notches in 60 seconds.

I have the newer black belt with unknown time on it; I've cleaned the belt, motor grooves and platter grooves. I get power from a dedicated 15amp plug, through an Audience AR-6 conditioner and stock power cord to the motor. I've tried using different notches on the upgraded 300 rpm motor pulley, with little effect.

I suppose the cheapest experiment is to buy a new belt, and lube the spindle bearing (for which I'll have to purchase oil) and see if that changes things. Short of buying the VPI SDS, are there any other actions which may help here for little money? Perhaps a used Variac would essentially do what the SDS does?

Your constructive feedback is appreciated.

Regards,

Bryn

I'm not sure how familiar you are with your TT. Do you know that you can vary the speed in small but noticeable increments by moving the belt up and down on the spindle? The larger part goes faster, the smaller part slower.

Just checking - it would suck to go through gyrations and miss this important detail.
