V Block Lenco L75 L76 L78 B52 B55 GL69 GL75 GL78 Tonearm Bearings Replacement. Perfect for replacing the old yellow crumbly ones which have restricted the vertical movement of your arm. These new soft silicone V blocks will make your arm's vertical knife edge movement perfect again. The last photo shows the destroyed old yellow blocks once removed. The previous 2 photos show one new block and the better of the old blocks in their positions on the arm of my Lenco L75.
