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.

< DECK SECTION > 10. Tape Speed Adjustment (DECK 2) Settings : � Test tape : TTA�100 � Test point : TP8(Lch), TP9(Rch) � Adjustment location : SFR1 Method : Play back the test tape and adjust SFR1 so that the frequency counter reads 3000Hz ± 5Hz and ±45Hz (REV) with respect to forward speed. 11. Head Azimuth Adjustment (DECK 1, DECK 2) Settings : � Test tape : TTA�330 � Test point : TP8(Lch), TP9(Rch) � Adjustment location : Head azimuth adjustment screw Method : Play back (FWD) the 8kHz signal of the test tape and adjust screw so that the output becomes maximum. Next, perform on REV PLAY mode. 12. PB Frequency Response Check (DECK 1, DECK 2) Settings : � Test tape : TTA�300 � Test point :TP8(Lch), TP9(Rch) Method : Play back the 315Hz and 8kHz signals of the test tape and check that the output ratio of the 8kHz signal with respect to that of the 315Hz signal is within 5dB. 13. PB Sensitivity Check (DECK 1, DECK 2) Settings : � Test tape : TTA�200 � Test point : TP8(Lch), TP9(Rch) Method : Play back the test tape and check that the output level of the test point is 140mV ± 3dB. 14. REC/PB Frequency Response Adjustment (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8(Lch), TP9(Rch) � Input signal : 1kHz / 8kHz (LINE IN) � Adjustment location : SFR451 (Lch) SFR452 (Rch) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at the TP8, TP9 becomes -20VU. Record and play back the 1kHz and 8kHz signals and adjust SFRs so that the output of the 8kHz signals becomes 0dB ± 0.5dB with respect to that of the 1kHz signal. 15. REC/PB Sensitivity Check (DECK 2) Settings : � Test tape : TTA�602 � Test point : TP8(Lch), TP9(Rch) � Input signal : 1kHz (LINE IN) Method : Apply a 1kHz signal and REC mode. Then adjust OSC attenuator so that the output level at TP8, TP9 becomes 0VU. Record and play back the 1kHz signals and check that the output is �2dB ± 3.0dB. < FRONT SECTION > 16. µ-CON OSC Adjustment Settings : � Test point : TP7 and GND � Adjustment location : L331 Method : Insert AC plug while pressing POWER and TUNER function keys. Adjust L331 so that the frequency atthe test point is 153.84Hz ± 0.15Hz.
Method : Set to AM 1602kHz and check that the test point is 2052kHz ± 45Hz. 2. MW VT Check Settings : � Test point : TP1 (VT) Method : Set to MW 1602kHz, 531kHz and check that the test point is less than 8.0V (1602kHz) and more than 0.6V (531kHz). 3. LW VT Adjustment Settings : � Test point : TP1 (VT) � Adjustment location: L942 Method : Set to LW 144kHz and adjust L942 so that the test point is 1.3V ± 0.05V. Then set to LW 290kHz and check that the test point is less than 8.0V. 4. FM VT Check Settings : � Test point : TP1 (VT) Method : Set to FM 87.5MHz, 108.0MHz and check that the test point is more than 0.5V (87.5MHz) and less than 8.0V (108.0MHz). 5. MW Tracking Adjustment Settings : � Test point : TP8(Lch), TP9(Rch) � Adjustment location : L951(1/3) ...................................... 999kHz Method : Set to MW 999kHz and adjust L951(1/3) so that the level at the test point becomes maximum. 6. LW Tracking Adjustment Settings : � Test point : TP8(Lch), TP9(Rch) � Adjustment location : L941, TC942 Method : Set up TC943 to center position. Set to LW 144kHz and adjust L941 so that the level at test point becomes maximum. Then set to LW 290kHz and adjust TC942 so that the level at test point becomes maximum.
