Took the motor board cover off my 'HW19. When I swithched from springs to sorbathane pucks it lowered the plinth and the pulley from the SAMA starting to rub against it. I suppose I could raised TT and put the cover back on, but what good to these cover's serve? None of the other VPI motors have covers. My belt rides a little higher on the platter, but so what? I've also heard these covers are just one more thing to vibrate. Doesn't look as nice, though. Any one have this experience?
