High-quality scanning. Detailed description. Recommend for all technician. A+++
;
This is a good quality scan of the original Service Manual from Nordmende, Germany. Contains the circuit diagram, PCB layout, adjust/tune instructions as well. It is NOT in English but in GERMAN language! That was quite right for my german friend from the lower east side in Berlin.

Received via e-mail this PDF manual is worth the money. This is a quality scan of a manual in excellent condition and is just as good as having the original manual in hand. I have later seen the original manual and it was printed in colour, but this particular manual is black & white but scan resolution is high end quality! All drawings and pictures are presented in great detail. So, nearly perfect score in my opinion.
If you own the turntable you also should own the manual!

I was very satisfied with the service manual I ordered and downloaded. I will definitely buy again from this seller.

Great product. Recieved it fast...exactly as advertised.
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.
