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!
