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!
very fast detailed and accurate hope to do business again

CD CLOCK ADJUSTMENT PROCEDURES
(All segments on FL tube light on) 3. Adjust trimmer capacitor C703 so that the reading of frequency counter becomes 524.288 kHz 1Hz.
Preparation 1. Connect frequency counter to the terminal TP01 on main PC board (NAAR-6875) Set trimming resistors R123 to center. 2. Press and hold down MEMORY button , then press the DISPLAY button.
Focus gain adjustment 1. Set output of the audio oscillator to kHz and 1 1.5 VP-P 2. Connect the oscilloscope and audio oscillator as shown below. (Refer to Fig-1) 3. Load test disc YEDS-18 on tray and play the track 2. 4. Adjust trimming resistor R123 so signal 2 on the oscilloscope becomes 1.25 times of channel 1. (Refer to Fig-2)
