This is an Original MCS JC Penney 6402 / BSR Quanta 400 Anti-Skating Knob Turntable Stereo Part. This was removed from a MCS JC Penney 6402 which I believe is almost identical to a BSR Quanta 400. This may fit other models. Please be sure it is correct for your application before purchase. It measures 3/4″ wide x 5/16″ deep. It is in excellent Condition. See all pictures for condition.
