The Service Manual for Sansui AU-9500 was very helpfull, in complete and in good printable condition.
Thanks.

Dear Sir,
Document is original service document of sharp. I had a problem with the door contacts. Fuses where blown. With the manual in a few minuts is was clear what the problem was.
Manual was of great help.
With kind regards,

The scan is clear and well readable with very few weaker spots, usually on black background with white letters, but with enough zoom those spots can be read.
Printout is clear, the manual is complete and has all pages scanned.
I would give 5 stars, except that it is not in color, and the schematic and PCB pages are scanned on multiple pages. The document is locked (except printing) so the pages can not be extracted to compose them together for printing on the large plotter
It is worth the price tag.

let's say first that i do not need to have a credit for my opinion, i am a retired sparkie and i voluteerd to fix an electronic device for a local "Youthgroup",as no diagram was present i checked the "net" and gambled on this site and paying some fee via PayPall, i was gladly surprised that the manual arrived as was stated, GOOD SHOW, and best wishes, John

I had been looking for a Manual for my CS2150 for quite a while -- in fact I had just about given up. I saw this site and decided to download the Manual. When I Received it by Email I was really pleased with what I got, with the result that My Kenwood 'Scope is now 100% repaired and working well. As an AV Serviceman, you need a good 'scope, and thanks to this site, and the Service Manual, I have been able to repair it. The Manual was a copy of the Factory Original and the copy was very clear, especially in the area of the Circuit Schematics, where You really need to be sure of what You are looking at.

ADJUSTMENT OF TAPE DRIVE TRAIN
1. Tape run rough adjustment 1 Remove the cassette housing control assembly. 2 After shortcircuiting TP801 provided at the center (facing to the main PWB), plug in the power cord. 3 Check and adjust the position of the tension pole. (See page 15.) 4 Check and adjust the video search rewind back tension. (See page 15.) 5 Connect the oscilloscope to the test point for PB CHROMA envelope output (TP201). Set the synchronism of the oscilloscope to EXT. The PB CHROMA signal is to be triggered by the head switching pulse (TP202). 6 Set the alignment tape (VROCPSV) to play. (Put a 500g weight on the cassette tape to prevent lift of cassette tape.)
Guide roller Cassette Tape
Notes: 1. Previously set the tracking control in the center position, and adjust the envelop waveform to maximum with X value adjustment nut. Thereby the tape run rough adjustment is facilitated. 2. Especially the outlet side envelope waveform must have higher flatness.
Figure 4-32. 2. Adjustment of A/C head height and azimuth 1 Perform the initial setting of A/C head position by the method stated in "Page 18 Replacement 3". 2 Connect the oscilloscope to the audio output terminal. 3 Using the alignment tape in which 1 kHz linear audio signal has been recorded, adjust the height screw so as to get max audio output. 4 Using the alignment tape in which 6 kHz linear audio signal has been recorded, adjust the azimuth screw so as to get max audio output. 5 Repeat the above adjustment steps 3 and 4 a couple of times. Finally take the step 4 again.

Weight of 500g
Figure 4-31. 7 Press the tracking button (+), (�) and change the envelope waveform from max to min and from min to max. At this time make sure that the envelope waveform changes nearly parallel. 8 Unless the envelope waveform changes nearly parallel, adjust the height of supply side and take-up side guide roller so that the envelope waveform changes nearly parallel. (For envelop adjustment procedure refer to Figure 4-35.) 9 Turn the tilt screw to remove the tape crease at the fixing guide flange. Playback the tape and check for tape crease at the fixing guide flange. (1) If there is no tape crease Turn the tilt screw clockwise so that tape crease appears once at the flange, and then return the tilt screw so that the crease disappears. (2) If there is tape crease Turn counterclockwise the tilt screw so that the tape crease disappears. (Reference) If the tilt screw is turned clockwise crease appears at the lower flange.
For X value adjustment Adjust the X value, turning the geartype screwdriver.
Figure 4-33. 3. Tape run adjustment 1 Connect the oscilloscope to PB CHROMA envelope output test point, set oscilloscope sync to EXT, trigger-input the PB CHROMA signal (head switching pulse). 2 Rough adjustment of X value Tentatively fix A/C head arm screws 1 and 2 by the method described in Page 18 "Replacement 3". Playback the alignment tape (VROCPSV) and shortcircuit TP802. As a result the auto-tracking is automatically cancelled, so that the X value adjustment mode is set. Move the A/C head with the X value adjustment gear driver (JiGDRiVER-6) by the method shown in Figure 4-33, and adjust the A/C head so as to get the maximum envelope waveform. (Note: When the A/ C head is adjusted, adjust so that the maximum envelop waveform is obtained nearest the position of initial setting made in Page 18.)
