A Turntable Belt is a building masterpiece, an instrument of music and a melodic fortune. These standard belts are not produced for the specific brands and models yet rather a progression of sizes that fit an assortment of brands. To work out what estimate you require you should gauge the breadth of the sub platter. The sub platter is the barrel shaped segment on the underside of the platter that the belt goes around. On a few turntables, it is a different thing and the platter lifts off it.
