VPI motor makes loud pops when turned on & off

Can someone suggest a possible fix for this?
I have the large 300 rpm Aries motor with heavy gauge grounded plug, which appears to be fine. The switch is on the side of the motor. It is plugged into the same outlets as my other components. I can mute the signal completely each time I shut it off and turn it on, (for each lp side) but it is really annoying.
Suggestions are very much appreciated..

Thanks,
Joe

The switch to the motor is arcing. Either the capacitor at the switch is no longer functioning, or you need to use a higher value capacitor. This appears to be a common problem with VPI motor switches. I believe they recommend replacing the .001 uF cap with a .01 uF cap (you would be looking for a high voltage ceramic cap), but I am not sure so please check with VPI.

The value of the cap should be .68u 400v. You should be able to find it in RadioShack. Capacitors are not very precise. Any value around .68u will work. Just make sure it is 400v or higher.

It has (1) F.001K 660PP and also (1) .68uf which I believe is for the motor phasing. Both look absolutely new, but I guess that does not mean they are good..
I will try to replace the F.001K.

Question: Can I use a .0022 600 Mylar instead of the .001?
I ask because I have one right here..

Thanks..

Motor runs fine, but still pops as before with the .001
