I did a search for a belt place and ordered a belt from them instead of Tascam who wanted 15 times as much for the same belt. I’m at work right now and don’t remember the name of the company. Do a search. Measure the diameter of the pulleys and the distance between centers, including any turns around other pulleys, to calculate the belt length. Calipers or something similar will come in handy for measuring. Even a piece of string or something with similar body as the belt thickness will work. I used AutoCAD to figure mine, but it can be done without it. I believe the belt I did buy cost me a whopping $1.68, plus shipping.
