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!

3.4.1Description of procedure:
3.4.1.1Diagnosis
Check the output frequency of the TCXO using the level-2 testing program for S10. Switch off the �CMD in Use� option in the config file (S6xx.CFG or S611.INI depending on the version of the testsoftware) and restart the program. Start the S10 test, when the program says �Check power and phase of external antenna with your GSM-Tester�, switch the CMD to �LOCAL� mode and enter the �MODULE TEST�. On the CMD display you can see the frequency error of the handset. (Make sure that the CMD is on channel 124, power level 5!) If the frequency error is higher than 2kHz, the TCXO has to be replaced.
3.4.1.2Repair by component change
Use hot air blower to remove defective TCXO. Avoid excessive heat! Watch surrounding components! Resolder new TCXO afterwards.
