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

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.
Mine did the same thing. First plug the motor directly into the wall to make sure it is the SDS and not the motor. Then cycle the SDS on & off a couple of times and see if you can get the table to run at 45rpm. Mine eventually started to work again after going up & down with the voltage & frequency. I use the on/off switch on the turntable and always give the clamp a little turn to get the momentum going, have not had a problem since.
I connected the table to the wall and it works fine. Seems SDS is not putting out enough juice but it working fine. Anybody know what to do with the SDS?
The SDS should be directly connected straight to an outlet, not another power conditioner.

You left out some details. Does the SDS read 115V when you first power it up, and when first powering up the motor on the HW-19? It is supposed to, then ramp down shortly after to a pre-selected voltage. Mark
