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!
Clear and concise. Saved me a lot of time and money.
Superb manual. Exactly what I ordered and made available in a very timely manner.
very fast detailed and accurate hope to do business again

5. NOTE FOR REPAIRING SERVICE
This modelâs power circuit is partly different in the GND. The difference of the GND is shown by the LIVE : ( ) side GND and the ISOLATED(NEUTRAL) : ( ) side GND. Therefore, care must be taken for the following points. (1) Do not touch the LIVE side GND or the LIVE side GND and the ISOLATED(NEUTRAL) side GND simultaneously. If the above cau-

tion is not respected, an electric shock may be caused. Therefore, make sure that the power cord is surely removed from the receptacle when, for example, the chassis is pulled out. (2) Do not short between the LIVE side GND and ISOLATED(NEUTRAL) side GND or never measure the LIVE side GND and ISOLATED(NEUTRAL) side GND at the same time with a measuring apparatus ( oscilloscope, etc.). If the above precaution is not respected , a fuse or any parts will be broken.
