VPI HW19MKIV huming motor


I'm hopefull somebody knows whats going on with my table.
My SDS is putting out the usual 72VAC 60Hz. But my table won't turn. When I touch the table spindle I can feel it vibrating but will not turn. Is it dead or dying?
Thanks much for the help, Riqe

Does it spin when plugged directly into the outlet?
Most a/c motors do not like starting at low voltages but are fine to change once it is spinning. Are you using any other power conditioning before the SDS?
Check that the pulley has not become loose on the shaft.. There is a tiny allen set screw in the side of the pulley that may have come loose. See if you can pull the pully up off the shaft.
I have a PS Audio Power regulator to where the SDS is connected to. Never been a problem. Will check the pulley but don't think its the problem.
