Up for sale is a factory issued Service Manual for the Luxman K-105 and K-405 Cassette Tape Deck.  This manual includes at a minimum: Specifications, Schematic Diagram, Circuit Board, Alignment/Adjustments, Exploded View and Parts Lists. Very good shop used condition, shows a little wear.  This is an original copyrighted document.  I charge a shipping fee so that I can combine shipping for those that want to take advantage of purchasing more than one item.
I pack for safe shipment.
