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

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
Spaninc,

What PS Audio are you using?
Is it is the older style like I use the PS300 and you are using it with the SDS or any a/c motor make sure Multiwave is disabled. A/C Motors do not like Multiwave an can cause harm to them with or without the SDS. If the newer models also has any type of multiwave turn it off.
