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!

very fast detailed and accurate hope to do business again
1. Adjusting Tape Speed
Requirements Test Tape: TTA-100 (3kHz) Test Point: HP OUT Adjustment Point: SFR 1 1) Insert the test tape (TTA-100), FWD play back the centre of the tape and adjust the SFR1 until it becomes 3,000Hz±10Hz. 2) RVS playback and check that ±45Hz is added according to the FWD speed.
2. Checking WOW & FLUTTER
Requirements Same as number 1. 1) Set the indicator to JIS and the mode to W RMS (WTD) of the WOW & FLUTTER. 2) Playback the centre of the test tape (TTA-100) and check that it is below 0.15%.
3. Adjusting Head Azimuth
Requirements Test Tape: TTA-300 (10kHz) Test Point: SP OUT (Lch/Rch) Adjustment Point: Head Azimuth Screws 1) Set the V mode of the oscilloscope to ADD. 2) Insert the test tape (TTA-300), FWD playback the centre of the tape and adjust, using the head azimuth screws until the waveform of the oscilloscope has reached the maximum when playing back at 10khz. 3) Reverse the tape, RVS playback and adjust, using the head azimuth screws until the waveform of the oscilloscope has reached the maximum. 4) After the adjustment, bond lock (1600B) the screws.
4. Checking Playback Frequency Reponse
Requirements Test Tape: TTA-300 (315Hz/10kHz) Test Point: SP OUT (Lch/Rch) 1) Insert the test tape (TTA-300) and playback 315Hz and 10kHz. 2) Use the 315Hz output level as a standard, check that the 10kHz level is within ±3dB.
5. Checking Playback Sensitivity
Requirements Test Tape: TTA-200 (400Hz) Test Point: SP OUT (Lch / Rch) 1) Insert the tape (TTA-200) and playback. 2) Check that the output level is within 2.8V±3dB.
6. Adjusting the REC / PB Frequency Response
Requirements Test Tape: TTA-602 Test Point: SP OUT (Lch / Rch) Input Point: AUX (1kHz / 10kHz) Adjustment Point: SFR851 (Lch), SFR852 (Rch) 1) Attenuate the output of the attenuator by 20dB to prepare for No.3 2) Insert the test tape (TTA-602) and record 1kHz and 10kHz alternately from AUX. 3) Playback the tape, adjust SFR851 (Lch) / SFR852 (Rch) until the playback output level of 10kHz is within ±0.5dB according to the standard when the playback output level of 1kHz is used as the standard.
