 SX990 PIONEER Service Manual by Peter Di Trolio;
The item received was as described, as expected. I was pleased with the order. Thank you.
 DN-M2000R DENON Service Manual by Dennis Kronenberger;
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!
 SC1000 OKI Service Manual by Steven Lewis;
Clear and concise. Saved me a lot of time and money.
 SM1000 MARANTZ Service Manual by Steven Lewis;
Superb manual. Exactly what I ordered and made available in a very timely manner.
 KVM2150K SONY Service Manual by NIKOLAOS PASATAS;
very fast detailed and accurate hope to do business again
