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 :)

I was thinking I will never find this manual. User-Manuals had saved my Teac V-7010 which is full of specific functions. Superfast service, excellent document. Thank you very much!

I downloaded this product and looked through it quickly with Adobe Reader v9. It is clean and a good copy. Some scanned pages are not perfectly square, but that is a minor complaint. The document schematics and board diagrams are easy to read, of good contrast. The whole file downloaded quickly. This is a good service! Sony charges about $100 for the printed version of the same manual. It is still available through their print-on-demand pro parts system, but why would you do that?
