VPI motor popping noise upon startup/shut off


Hi All;
Has any one successfully filtered out, or stopped the popping sound commong from the VPI Aries Scout stand alone motor which occurs during start up and is louder during shut off of the motor? This noise is audible through the speakers.

The table is grounded to the Art Audio Vinyl One phono stage, and like all the front end gear, the power cords our shielded and have Hospital grade connectors. Also, all the front end gear is going into a Monster 3600 MKII power center, which is going into an APC Battery Back UP. This double filtering works great with the sound, and protects against our numerous lightning disruptions and brown-outs.

Perhaps there is a single recepticle power filter.

Thanks for looking

check out this thread: http://forum.audiogon.com/cgi-bin/fr.pl?htech&1286763065. Exact same problem. I believe there was a way to fix this in there if I remember correctly. Good luck.
The popping sound is comming through the Velodybe DEQ 12R subwoofer, which has a shielded power cord. The sub does not have a third prong. It shares the home theater power outlets. The sub interconnects are currently connected from the Audio research LS2B MKII line stage preamp. There is no popping comming through the 2 channel dedicated audio system.
I've done the fix. Call Harry Weisberg at VPI and he'll guide you through it. You need to go to Radio Shack and get a different capacitor (.06 vs. what's in there--the exact value I don't remember). It requires you to take off the long plate underneath the chassis and remove one capacitor while installing the other. No tools required--10 min. max to do the job. It was quite easy and there's NO pop anymore--dead quiet. It will cost you less than $2.00 and a trip to RS.
A quick fix might be to have the volume all the way down at motor start-up and stop.
