SDS speed control


I have a VPI Aries 2 with the SDS. Recently aqiuired a strobe light and disc. However, I can't make the lines stand still. No matter the level of adjustment of the Hz there is a slow spin to the right. Any ideas out there would be appreciated.

Have you changed, or applied talc to your belt & lubed the motor lately? Cleaned the circumference of the platter and pulley, with alcohol? If your belt is slipping significantly; no amount of correction from the SDS will help.
Shakey- Belt slippage doesn't have to be, "severe" to show with a strobe/disc and not everyone can discern minor speed/pitch variations aurally. The OP did say, "a slow spin to the right."
