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.

Downloaded the Service manual OK of the Technics Piano and have now repaired it and its going fine. Excellant; thank you for the fine servce. A.M

This site is working fine! Did buy a manual for SX-EX25L and after a while I could download it and fix the problem. Nice and easy!
