Bcr,
I can't give you the technical reasons that you're having problems with your Nak but will just say that there is more going on under the hood of your machine than just a few belts
and pulleys. Typically, people buy used machines and think that they can update them easily with parts bought on Ebay. I
just had my RX-505 re-worked by a local tech (Willy Hermann).
It wasn't cheap but it sounds and works like new. Get some
professional help and I think you will be glad you did. I also
have a CR-7A and can tell you that it is worth the investment.
