Correct triangular / wedge-shaped belt for the tracking servo motor in the following Bang & Olufsen Beogram tangential record decks:
The original belt is wedge-shaped (triangular cross-section) for the simple reason that it requires less torque to run around the small diameter pulley on the servo motor than a similar square or round belt. No square or round (cross-section) belt will run as the original part.
A belts elasticity and friction is always very important, but even more so is the choosing of rubber material with the correct density for this belt. Easy running is essential in allowing the tonearm carriage a nice and smooth travel and avoid any jerking motions during playback.
This belt is exactly like the original; Correct shape, correct size, correct friction, correct elasticity, correct density.
This belt is a direct replacement for original Bang & Olufsen part# 2732045
