Let me let y'all in on a little secret- Projector-Recorder Belt Company in Whitewater, Wisconsin manufactures alot of OEM belts. They also make alot of the replacement turntable belts on the market today. I stumbled across the company 25 years ago while going to the University there. (Of course, "stumble" is the operative word as they are located a couple of blocks from the downtown bars!) Got a replacement belt for an Empire 698 there when no one else had one.
