Once again owner-manual.com has saved the day for me, and come through with the manual I need. I looked other places too, and couldn't find it anywhere. Thank You owner-manual.com!!! You're the BEST!

very good quality that can be magnified several times, and it remains readable.
For sure I will return next time the need for a service manual arise.

The service manual is really great - thanks to it I was able to install the laser unit and thus "save" my CD-player, which seemed to be impossible before I had the manual.
