Up for sale is a factory issued Service Manual for the Yamaha  P-90M Turntable.  These manuals generally include at a minimum: Specifications, Schematic Diagram, Circuit Board, Alignment/Adjustment (as applicable), Exploded View and Parts Lists. Very good shop used condition, note the two tears along the top edge of the cover.  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.
Tired of your improperly packed purchases getting damaged in shipping? I pack with care. I use a full sheet of rigid protective material, a plastic sleeve, a 'Please Do Not Bend' sticker, and free Delivery Confirmation. All of my items are originals, I do not deal in reproductions. I am happy to ship internationally.
