Is there a source of rubber belts in various lengths from 2" upwards in increments of 1/2", rather than going to a specialist electrical components supplier to buy such belts in highly-priced packages?
I have two cassette tape machines which have both given up the ghost at about the same time (rubber belts having taken on the physical characteristics of liquorice), and it seems that I'd get a better deal if I were to buy the belts from whoever the belts from whoever specialist electrical components supplier buys then from.
