Apparently a common problem with the Phillips CDM-9 transport is that the white, belt-driven gear tray wheel breaks. Well, my trusty RCD-975 is based on this transport and after 10+ years the gear finally broke tonight. It's not like I don't have enough broken pieces of equipment to work on. But I guess it could be much worse. At least the part is available and easily replaceable. Whew. I found one off of ebay for a reasonable price. There are probably other sources.
