Up for sale is a factory issued Service Manual for the Onkyo TX-DS484 and TX-SE570 Receiver. These manuals generally contain at a minimum: Specifications, Adjustment/Alignment (as applicable), Schematic Diagrams, Exploded Views and Parts Lists. Very good condition. This is an original document. Don't settle for hard to read pirated copies or PDF's.
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.
