Hi y'all, I was going to sell my NAKAMICHI DR-2 Tape Deck on Ebay. I put a tape in it this morning, and it wouldn't move the tape. Then it started very slowly, and then ran great. Do you think I need to clean the ROLLERS and SPOOLS behind the front panel? Or is the drive belt giving out or the drive motor? It runs perfect otherwise. I can't sell it if there might be an even BIGGER issue. Is there something else that may be wrong, that I not thinking of.
