Hello, I have an Beogram 4000. Its serial number indicates that it is an early model, i.e. the one with the round carriage servo belt, and indeed the belt currently installed has a round cross section. This can be seen in the picure below. It is also obvious that the belt is very loose, most probably because it is the incorrect belt(?). Rather surprisingly, the carriage transport works well, even with this floppy belt. B&O's service notes indicate that this belt should be replaced with the new triangular belt, together with new pulleys. However, while the belt and new aluminium carriage shaft pulleys are available from DKSoundparts, the same cannot be said for the carriage motor pulley. However, looking at the pulleys currently on the turntable, they both have distinctly triangular grooves, which makes me think the pulleys have already been replaced at some stage. This can be seen in the photo. The question I have, can anyone tell me whether these pulleys are for the new triangular belt, or are they still the originals? If not, what is the difference between the original and new pulleys? Given the age of the pulleys, and the reputation the carriage pulley has for disintegrating, I would like to replace them. If I do need to replace the motor pulley, does anyone know of a source for these? Many thanks Peter   Login to view image Login to view image
