Why does the VPI motor thump

Why is it when I turn off my VPI motor I hear a thump through the loudspeakers? The only direct connection to the stereo is the belt.

Either yours has burned out or isn't there or isn't large enough. Contact Mat at VPI and he'll send you the one you need. http://forum.audiogon.com/cgi-bin/fr.pl?htech&1221786906

I was a VPI dealer for many years and this goes all the way back to the HW-19 series. I've personally owned well over 50 different VPI tables and most, but not all of them did this. I think it has a lot to do with the preamp and interconnect cables also. Many owners have stated that changing interconnects solved the problem. It's not a VPI problem per se, but just the luck of the draw with associated equipment.
