The manual is well organized and is easy to read. The chapters are following normal way to proceed.

This scanned manual is well done in that most all the pages except for one is straight and clear- the way I would do them. One page was upside down but that happens. For the money that is charged on this site you get a pretty good deal. Now with complex repairs, I still prefer to us paper manuals which I have to buy at stereomanuals but the one I got here was much less than the $45 he was charging but this is a larger than normal manual for three different units. I am a picky manual user because I have used original manuals from Sony and Teac.

Very useful service manual, was exactly what i needed.Good quality,reasonable price.Thank you.

Acurate informations inside the SM and I could repair my old Sansui SC-3330 without any problems. Thanks.

I used it to repair a NAD 7030, but unfortunately, the 7045 is different !
But documentation was useful.
25L-M100/180/S100/180 CL25M10,CL25S18
MTS ADJUSTMENT
(Only for 25L-S100/180, CL25S18)
MTS Level Adjustment
1. Feed the following monaural signal to pin (14) of IC3001. Monaural signal : 300Hz, 245mVrms 2. Connect the rms voltmeter to pin (39) of IC3001. 3. Enter the service mode and select the service adjustment "M01". 4. Adjust the data so that the rms voltmeter reads. 490 ±10mVrms.
MTS VCO Adjustment
1. Keep the unit in no-signal state. 2. Connect the frequency counter to pin (39) of IC3001. 3. Connect a capacitor (100µF, 50V) in between positive(+) side of C3005 and ground. 4. Enter the service mode and select the service adjustment "M02" 5. Adjust the data so that the frequency counter reads. 62.94 ±0.75kHz.
Filter Adjustment
1. Feed the following stereo pilot signal to pin (14) of IC3001 . Stereo pilot signal: 9.4kHz, 600mVrms. 2. Enter the service mode and select the service adjustment "M03". 3. Adjust the data at the point where "OK" appears on the screen. The "OK" represents the approximate center of the adjustable range of the data.
Separation Adjustment
1. Connect the rms voltmeter to pin (39) of IC3001. 2. Receive the following composite stereo signal 1. Composite stereo signal: 30% modulation, left channel only, noise reduction on, 300Hz 3. Enter the service mode and select the service adjustment "M04". 4. Adjust the data until the AC voltage reading of the rms voltmeter is minimum. 5. Receive the following composite stereo signal 2. Stereo signal: 30% modulation, left channel only, noise reduction on, 3kHz 6. Enter the service mode and select the service adjustment "M05". 7. Adjust the data until the AC voltage reading of the rms voltmeter is minimum. 8. Take the above steps 1 thru 8 again for fine adjustment.
