If your turntable is not listed, first look for a close match in model number. Or, take careful measurements of your old belt's inside circumference, width and thickness.
Make the measurements with the belt lying flat and unstretched. Use a paperclip to mark your starting point. Measure in inches to match model; one inch=25.4mm. Also, make note of how loose the old belt is while installed in the turntable. Does it slip? How much side-to-side deflection is there in the open section between the spindle and the platter? Depending on how badly stretched out your old belt is, deduct 5 to 10 percent from the circumference. If the belt is broken or missing, use a piece of string (wrapped without slack, but not stretched) to measure the proper circumference, and then deduct 10 percent to allow the new belt to stretch into place. Go to the Belt Specifications Chart to find a suitable replacement.
