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 Outline
the Document
Density
The copier is equipped with an automatic density control (AE) mechanism, which controls the DC component of the developing bias to suit the density of the document. As long as the document is uniform overall, copies free of fogging can be made by varying the DC component of the developing bias. The AE sensor is mounted inside the lens unit and consists of a photodiode and operation amplifier. 2. Mechanism
During the initial rotation (INTR), the scanning lamp goes ON, and the scanner moves forward about 12 cm and reverses. The microprocessor on the DC controller, while the scanner moves in reverse, reads the output of the AE sensor 80 times at intervals of 1 mm. The area measured at the time is as shown in Figure 3-20.
Remove the upper front cover, and close the, copier. Turn the power ON, and open the delivery unit cover. Place a blank sheet of paper (copy paper) on the copyboard, and close the document cover. Hold the REDUCTION/ENLARGEMENT and ZOOM MODE keys down, and close the delivery unit cover. . The copier enters the AE adjustment mode. . The count is �00�. 6) Select the DIRECT copy mode, and press the COPY START key. * The scanning lamp goes ON, and the scanner moves forward to the copy paper. . The count indicates the output of the AE sensor read by the microprocessor. 7) Turn VRIOI on the DC controller until the count is �55�. Note: The problem detection circuit of the lamp regulator will be activated if the scanning lamp remains ON for 15 to� 30 seconds to turn the lamp OFF. If the lamp goes OFF before the count indicates �55�. turn the power OFF and ON, and repeat step 3) and onward. 8) 9) Note: Press the CLEAR/STOP key. Turn the power OFF and ON.

Area
Measured
See Figures 3-21 and 3-22 for the relationship between the count indication and the input of the microprocessor or the DC component of the developing bias.
The microprocessor calculates the average of the density data of the 80 points and controls the DC component of the developing bias based on its result.

Adjustment ov
The following adjustment is performed when the DC controller or AE sensor is replaced. 1) Turn the power OFF, open the copier, and remove the drum unit.
