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!!

Yes thank you i got the file i was after. There was a slight problem in my communication but it all worked out well.
A job well done.

Great manual...really saved me. The only problem is that I thought I would be able to download it directly when I paid for it but never received the download instructions until the next morning. The board trace pages were somewhat light also: really need to turn up the contrast on the printer before printing them. The schematic page was great; very clear! Well worth the money.

Measuring Waveform of Pulse Module Timing Adjustment
Timing adjustment of the pulse module control signal adjusts with the sustain pulse of eighth pulse (X DRIVE) and the ninth pulse (Y DRIVE) from the back of 6SF.

� Perform adjustment of waveform with a black mask screen. � It is easy to adjust when turned field AB offset to OFF (RS-232C command: OCN) in adjustment. Note: � Sampling rate of oscilloscope sets it more than 500MS/s in order to perform ns order adjustment. � Collecting calibration of probe before adjustment by all means. � Connect GND of probe measuring waveform to SUSGND terminal by all means. � Precise waveform is not displayed, and an adjustment gap may occur that does not collect GND properly.
When took waveform be each drive Assy unit, measure it at the fourth sustain pulse from the back except for a large width sustain pulse. Therefore, when measured both waveform of the X and Y drives together, it becomes the sustain pulse of 8 and 9 pulses from the back.
Waveform coarse adjustment
Measure the SUSOUT waveform When there is a gap with waveform of CH1 / CH2 of the part which enclosed in the following circle, adjust required VR to overlap the waveform.
