The item received was as described, as expected. I was pleased with the order. Thank you.

Superb rendition. Drawings (schematics) complete and unabridged. I do a great deal of vintage audio restoration. Documentation is essential for successful repairs. I have found sources over the years that offer good documentation, but rarely all that is necessary. Owner's Manuals has filled that void with complete and legible documentation. They have narrowed my "favorites" to a more manageable collection. This Denon manual in particular contained the latest revisions level, and offered alterations favorable to updating the item. The Illustrated Parts Breakdown (IPB) was well enough detailed to simplify part symbols and physical locations. You will not be disappointed!
