That info came directly from Harry at VPI during a phone call to him sometime ago. I did exactly what he said to do and that solved the problem, Took about 40 minutes of time from start to finsih. Most of that in dissasemby and reassemble the turntable. The part was .75 cents.

Ferrari,
If you had been a first first time caller would Harry have given you the same advice?
By the way VPI now aswers the phone Tuesday through Thursday.

LOL, I think you understood my comment.....
==========================
As for those who think VPI should install the capacitor, period....
Well if all audio equipment manufacturers built their equipment with double insulated power wiring then there would be a lot fewer ground loop hum problems.... That is for people who have ground loop problems.
As for VPI installing the .75 Cent part across the switch in every TT they manufacture I am sure they have a reason why they are not doing so. Could be a cost issue but I doubt it, jmho.....

Quote from
Link: "A sudden rise in voltage across the switch contact caused by the contact opening will be tempered by the capacitor's charging action (the capacitor opposing the increase in voltage by drawing current). The resistor limits the amount of current that the capacitor will discharge through the contact when it closes again. If the resistor were not there, the capacitor might actually make the arcing during contact closure worse than the arcing during contact opening without a capacitor! While this addition to the circuit helps mitigate contact arcing, it is not without disadvantage: a prime consideration is the possibility of a failed (shorted) capacitor/resistor combination providing a path for electrons to flow through the circuit at all times, even when the contact is open and current is not desired. The risk of this failure, and the severity of the resulting consequences must be considered against the increased contact wear (and inevitable contact failure) without the snubber circuit."
