Source for a new AR turntable belt:
Part Number: Panasonic SJY90080-3
This is a Panasonic belt that works very well in my opinion. Thickness – 0.020”, Width – 0.155, Length - Just Right.
This belt is wider by 0.020 and thinner by 0.010 than the stock belt but it works very well. No motor strain and it doesn’t pull the suspension off center. Very compliant.
I bought several of these to keep on hand as replacements for my AR "The Turntable".
I tried a belt from a seller on eBay and while the dimensions were correct the compliance (flexibility) was not. It caused the platter to shake and shudder upon start-up. Then I found this Panasonic belt and never looked back.
