Jeff,
Probably not belts then, although the last two belt sets that I received were not correct. One had a counter belt that was about two inches too long and the other had a capstan belt that was half as wide as the original. The seller may not have even replaced the idler since if you do it what is probably the correct way you have to remove the transport and the reel motor and reels which have some real tiny washers that you don't want to lose. I thought that I had a bad reel motor on one of mine but it turned out to be a bad capstan motor. One thing that you can do is is remove the cover and then the cassette door and blind plate behind the cassette cover. There are two screws on the blind plate and after you remove them you can wiggle the plate out and out of the way being careful not to damage the heads. To the left of where the right screw was and below the RS on the face plate is a micro switch. If you turn the 1200 on and depress this switch you can push the buttons and observe what is happening or not happening with the idler and reels.. In the case of the one I have in front of me the Idler does not make good contact so I put one on off of a K-1020 "organ donor" which has the same transport. Didn't work so now I am waiting for a replacement from Germany after waiting two months for one from Belarus which never arrived. If that doesn't work then I will take it in. Another thing you can do with the cover off is observe the capstan motor since it will be running when the power is on. Although the reel motor was replaced you can test that too by applying power to it. I cut up a cheap Harbor Freight multi-meter and connected the probes to the 9 volt battery wires and then you can touch the leads to the reel motor. I called my guy and talked to him and he said it could be several things beyond belts, one being the idler. Also if the light behind the cassette is out. Could be the sensor which could just be dirty if I understood what he was saying. Other than the idler I am not sure there is anything I would want to try. If you disassemble it to that point and can't find anything not working as it is supposed to then PM me and I will give you my guys contact info and he will talk you through what
you can do to try and figure it out. You will probably have to take it in but who knows? He is probably an hour and a half south of you. I have a Nakamichi RX-505 that I got real cheap that would not auto-reverse or play. I opened it up and knew that I didn't want to even try to fix it, so I called one of the Nak "wizards" and he said he doesn't do repairs because six months later they break down again, so all he does is overhauls. About $500 dollars and a five month waiting list. I put my name on the list and after four months decided to call my guy. He said he had done a few so I took it in. Took over a month but he tested and calibrated everything while I was picking it up. Total cost $55. Still haven't heard from the Nak guy and its been almost 8 months.
