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.

Great Service Manual, Very Complete, as advertised, Perfect, Thanks!

Idling Current Adjustment All power amplifier stage need idling current adjustment after the installation of TRAIT transistor. 1. Connect a voltmeter to CN11 with the correct polarity as indicated by the PCB silk print. 2. Adjust the preset, VR1 to get 8.8mV (Idling current = 20mA) at the voltmeter reading. 3. Repeat step 1 and 2 for all other channels.
