I have an old, old Aiwa TP-802 reel to reel player that needs a new belt in order to properly drive the receiving reel otherwise slack builds and jerks on the tape which I'm afraid will eventually stretch out what little stock I have beyond use. Let alone what I have that is actually worth playing and not just recording to. I can't see to find a source for them on eBay as per specific model matches but I was hoping someone knew of a way to find a generic replacement based on belt measurements.
