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!

Complete manual as pdf-file in very good quality. Very helpful and fast availability.

Complete service manual in very good scanning quality with all schematic and PWB graphics as well as assembly & maintenance instructions. A slight drawback is that the rastering of the PWB graphics sometimes makes it a bit difficult to follow fine traces, but no showstopper.
