Long out of production but now available in limited reproduction;
Exact correct belts for the tracking servo motor in 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 belt.
Easy running is essential in allowing the tonearm carriage a nice and smooth travel.
Also – and this is particularly important for the newest generation of
tangential decks, the type 59xx ones (3000,3300,4500,5005,5500,6500,7000,8500,9000,9500 and TX2)
– the choice of rubber material is immensely important;
It must not be too loose, or the belt will simply come off when running fast.
And it must not be too dense or vibrations from the servo motor will be transferred to the floating subchassis, to the platter, to the record, the needle and
your speakers.
If you fit a square belt or a round belt (anything but the real wedge-shaped thing) then each time the tracking motor runs it will be audible as a faint rumble in the background of the music. Needless to say this is quite annoying, – not only
during silent passages in the music, but particularly between tracks, where
there is no music and the tracking motor is very active.
The real belt – and of course this reproduction – was produced with this in mind.
This belt is exactly like the original; Correct shape, correct size, correct friction, correct elasticity, correct density.
This is not some random belt that merely “looks right” or “a substitute that seems to work”.
This is the real thing.
