Quick service response. A useful and very rare service manual with all details. I recomend this service.
;
I ordered this manual sometime in the afternoon and I received it on my e-mail the same evening.
This is a fantastically good and properly scanned copy of the original manual. All pages are of the same scale and they overlap each other. It means that you can print the manual and easily make it as a convenient paper manual.
The content of the manual is fantastic. Alignment descriptions, PCB layouts and elementary diagrams are explicit and precise. I immediately found what I was looking for. Thanks to this manual and Owner-Manuals.com my amplifier is alive again. Many thanx indded!
;
The manual was well-scanned and easy to read. As an added bonus, the Operator's Manual was bundled with the Service Manual!
I'd definitely use owner-manuals.com again.
;
Finally, i found one website, where i can download this service manual , and fix my hifi. The service manual is very good, and easy to download and to print.
 ;
Complete and very useful. Could have benefited from a little higher resolution on the schematic and layout diagrams for improved legibility.

4-3-2 To Adjust Tracking Gain (PLAY mode)
1. 2. 3. Connect the GND terminal of the oscilloscope to Vref and (+) terminal to AP2. Load and play the disc While the disc is running adjust the gain with WVR1 as shown below. Normal frequency Low frequency High frequency
---0 V
---0 V

VOLT/DIV : 0.2V TIME/DIV : 2mS
VOLT/DIV : 0.2V TIME/DIV : 2mS
VOLT/DIV : 0.2V TIME/DIV : 2mS
4-3-3 To Adjust Focus Gain (PLAY mode)
1. 2. 3. Connect the GND terminal of the oscilloscope to Vref and (+) terminal to AP1. Load and play the disc While the disc is running adjust the gain with WVR2 as shown in the following figure. Normal frequency Low frequency High frequency
---250mV ---100mV ---0 V ---0 V ---100mV ---0V
VOLT/DIV : 0.1V TIME/DIV : 2mS
VOLT/DIV : 0.1V TIME/DIV : 2mS
VOLT/DIV : 0.1V TIME/DIV : 2mS
4-3-4 To Adjust E/F Balance (PLAY mode)
1. 2. 3. Set TIME/DIV of the oscilloscope to 2mS. Set Volt/DIV of the oscilloscope to 0.5V. Ground the scope input and set to DC and then set the DC range. Connect the GND terminal of the oscilloscope to Vref and (+) terminal to center to AP2. Load and play the disc. Turn WVR1 counterclockwise to the minimum value. Raise WVR3 and adjust the waveform so that its middle comes to GND of the oscilloscope (or until the upper half of waveform becomes symmetrical to the bottom half, A=B) Adjust WVR1 (arrow) for normal sound.
4-3-1 To Adjust FOCUS BIAS(STOP mode)
1. 2. 3. 4. Set Volt/Div of the oscilloscope to DC 100mV. Ground the scope input and set the waveform to 0V, DC range. Connect the GND terminal of the oscilloscope to Vref, and (+) terminal to center of AP1. Set WVR4 to 0mV.
