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!

Good quality service manual.It has helped me to fix my FV1800,particularly for replacing the dial cord.The scheme is on A3 format and very readable.Thank.Olivier.
