Contains mechanism diagrams, parts lists and schematics for all worldwide versions of DC-X88Z. Also includes remote schematic etc. A few non-essential pages are missing such as specifications. Includes the mechanical and electronic calibration instructions for the tape decks.

Outstanding and fast service! I received service manual in a moment after order. Thanks to this manual I can use my printer again!

Henry Seiden - 02/26/2009

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?
