Excellent! I'm very pleased with quality of Sony DCRDVD-101 owner's manual. The manual has 148 pages and covers basicly everything!. Thanks again for great service!

Paul Brady - 01/03/2007

Talk about a lifesaver!!!!!!!!!!!! This schematic will also work for the Radio Shack DX-392. This is the full blown service manual complete with alignment instructions, schematics, and parts lists.

John Craig - 07/31/2006

Very nice site and the manual is great. A life-saver. Thank you so much!

Aaron Lawrence - 01/02/2008

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.

Essential for popping the top open and cleaning and replacing what needs repalced. One note: the Ornamental Panel is attached with some adhesive as well as screws and faders so don't be shy about prying it open.
