Yamaha TC-511S diagram

Hello all,

I'm in need of a schematic (or a complete service manual) for a Yamaha TC-511S, this is a sort of front load cassette deck from the late 1970's. (There is an opening in the front panel where you reach in and place the tape.) It has a problem in the Dolby circuit, and the board is very annoying to get at, so a board layout would be good too.

Anyone have one that they want to sell, photocopy or fax?

Thanks!
