Nice, really nice. I was happy to receive manual in true electronic form, instead of scanned original. This manual includes: Wiring diagram, circuit diagram, block diagram, PC board, adjustment, exploded view, PARTS CATALOG and more.. It's full color manual, not B&W or grayscale :)

PDF contains : - schematics, but a little un-sharp. - disassembly instructions, accurate drawings - description of test-modes

Great original Yamaha manual and no problems at all with the ordering process. Will definitely use this website again and would recommend it to anyone else. James Thorp

Just got this Manual downloaded... Scan is PERFECT! This is EXACTLY what I needed. However, please update your site info to state that it may take more than \"a few hours\" to have the download available after payment - - - I had to wait 4 days, in my case. Otherwise, I am very happy with this!!! Thanks! --- User-Manuals.COM comment We\'re sorry for delay, we had major problem with our download server, but all is ok now and downloads works as previous.
