VPI SDS question

1.the voltage display on my SDS sometime is at 72 and some time is at 84 is that normal?
2.almost every time I got the speed dead on , the next day when I check the speed is off. Is there anything I can do so I can get stable speed and don't have to check every time I listen.
BTW I have the 3 months old Classic, so the belt and motor should not be the issue and I use the KAB strobe disk.

I read somewhere here that it has to do with the classic motor,,, do a search or contact VPI.

Good luck.

No, mine does that and I use it with the Aries with Single Motor Flywheel as well as Scoutmaster and Scout with standard motors. I have no idea why it does this but others have noticed it and it was discussed on a recent thread.

The motor needs to be sent back to Harry for modification. Why VPI did not tell dealers that there was an issue with using the SDS with the Classic motor speaks to poor business model.
