Through some good karma I procured a NAD 6100 cassette deck recently. I cleaned and demagged it and ran several cassettes through it. I also tested the record function and found everything is working quite well. Here on AK I found several threads discussing where to purchase replacement cassette deck belts, so I opened my unit to see if I could replace them myself. The rewind/fast forward seems weak, so I assumed an old belt was driving that. Boy, was I wrong! Inside I find the capstan is belt driven and the ff/rw is direct drive off a separate motor! (see attached pics - the ff/rw motor is at the top of the second photo) There are rubber bits in the bottom of the case indicating some wear from the belt (3rd photo). The belt itself seems "loose". I can easily depress it with my finger, yet it has enough grip to drive the capstan with no noticeable wow or flutter! :headscrat The way the belt sits, I don't see an easy way of replacing it. It looks like I would have to separate the tape transport completely away from the deck proper. Anyone have any experience doing a belt replacement on this model? BTW, I called the local ULTIMATE ELECTRONICS today to ask about NAD cassette repair service only to be told "we don't work on those". I'm disappointed because I've had their "FAST TRAK" service people work on other gear for me. Anyone know of other service alternatives in the Twin Cities?
