Compatibility and belt position

Sony's PS-Q3 service documentation lists separate belts: reference 32, part 4-879-751-00; motor belt 4-905-529-01; and rotor belt 4-905-531-01. These are separate parts, not three names for one belt. This SBS 3.7 belt has not been established as the tonearm belt or as an equivalent of either other Sony part.

Please contact us with the original belt or part reference before ordering for a PS-Q3. No PS-Q3A or PS-Q7 compatibility is added.

Confirm the complete equipment model, revision, original belt position and dimensions before ordering. Disconnect power and follow the equipment service instructions. This listing is not a complete belt kit.
