Up for sale is a factory issued Service Manual for the Sony XR-510R Cassette Car Stereo.  These manuals generally include at a minimum: Specifications, Schematic Diagram, Circuit Board, Connections, Exploded View and Parts Lists. Very good shop used condition. This is an original copyrighted document.  Don't settle for hard to read pirated copies or PDF's.  I charge a shipping fee so that I can combine shipping for those that want to take advantage of purchasing more than one item.

This is not an Owner's Manual
 
I pack for safe shipment.
