I'm very satisfied with your manual service. Your website made it easy to locate the correct manual. Also the quality is great and I never had a problem reading the fine details.
Thanks again.

Good quality service manual German user manual. German user manual This is a quality scan of a manual in excellent condition and is just as good as having the original manual in hand

The manual for Sony LBT-D505 component stereo system is was excellent , with schematics, parts layout and parts list as well as instructions for adjustments for each component. Print was clear even when enlarged.
;
It's exactly a complete and very useful manual with all details what I needed. Thank you!I will come back whenever I need your manuals or schematics.

I searched EVERYWHERE looking for the manual/s on this "extinct" amp. Owner-Manuals.com made it available and for nearly nothing. Thanx to them, I can decipher the unknown cables and sort them out. Thanx, Owner-Manuals.com!!
