Yes, I am Perry, and I live in Richmond, Virginia, hence..perryinva. If the receipt is for a Marrs capstan belt, then you saved yourself $20 off the price of a repair, but there are 4 other mundane $2 belts on a 660zx, and any of them can prevent the deck from working, except the azimuth belt, which just affects the record head adjustment. If I were to guess, though, it is more likely that it is for the $2 cam belt, which is the easiest to replace, and usually the first belt to stretch and go, and prevents any function. A lot of people when they get a Nak deck of this vintage that doesn't work, try the cheap, easy belt fix first, but if the pinch roller arms grease has stiffened with time, which is fairly common on this vintage, if it hasn't been used regularly, then the deck will not work, and forcing the arms will usually strip them and destroy the transport. It requires careful removal of the arms after removing the transport and soaking the pivots to dissolve the glue like grease, with care taken to not force the pivot pins out of the transport base. Remember this is a 35 year old tape deck, that was around $1000 when new, a serious piece of gear at the time, and likely hadn't even been turned on for the last 15 years. IMHO, it is well worth the effort and $ to repair properly, as it is a great performer and looker. Since you got it for free, if you pay to have it restored, and the cosmetics are fine, then it is a no brainer (if you can afford the repair up front), as you could either recoup your investment and then some, selling it as a perfect deck, or have a very fine cassette deck that will give another 20 years of service, to try for a while and see if it is something you want in your system. Cassettes are not for everyone, but like so much vintage audio, it is an easy addiction for many, especially if you've never heard a TOTL Nakamichi before in a nice system. Like most people, I was never impressed with cassettes when they were popular, except as a portable media, but like most others, I never owned a great tape deck, and I found out rather quick, that judging cassettes on my car stereo was like judging vinyl on a cheap record player with a ceramic cartridge. After I rebuilt my first Nakamichi deck many years ago, I was hooked. It's just that to the non cassette savvy person, even cheap cassette decks, look pretty good, like some cheap all plastic turntables look good to someone that knows nothing about turntables. Just lifting up the 660zx tells you it was built as a serious piece of hardware, it weighs a ton compared to modern (late 1990) cassette decks, more than twice, normally, and it is often not even as large dimensionally.
