I am the original owner of a PX-101 that I cleaned up yesterday. The rails that the tonearm carriage ride on were quite gummy so I used cotton swabs and alcohol to clean them, and then I used a dry teflon lube that also cleans a bit. Working and sounding great, but I also need a replacement tone arm belt. If anyone has a source (US preferred, but will gladly do business elsewhere), or just the measurements (inside circumference, outside circumference and cross section size) it would be appreciated. It is working but the belt is a little stiff and a bit stretched so I do not think it will last. It is Luxman part #911598 if that helps.
