Radio shack has been less than helpful...
A source that sales small qunatities at a reasionble price would be appreciated.
R!
Your best bet may be to measure the existing belts (inside circumference, width or cross section, and wall thickness), subtract around 5% from the circumference to compensate for stretching of the old belt, and then purchase the closest-matching generic belt.
PRB seems to be the brand of choice for replacement belts. They carry flat (ribbon-type), round, and square cross-section belts in quite a variety of sizes.
Lots of online sources - Vintage Electronics carries some, or see
