Picked up one of these a week or so ago. It needed the belts replaced and the pinch roller mechanism cleaned up. From what I read here on AK that usually takes care of most issues. No such luck. It got everything working fine mechanically but the left channel does not play or record. The VU meters light up and the needles peg to the right then back to the left when I turn it on, but that's it. I can record with it but not the left channel. I read all the threads on this unit and do not see much about this problem. One thread talks about a similar problem and the author thinks it is related to tape/source monitor switch. I don't seem to have a problem with the switch. I was hoping someone could point me in the right direction. Cosmetically, it's not the greatest but if I can get it working for not much investment and learn something along the way, then that would be a good thing. Any ideas?
