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.

5. Rotate the [DISC/CHARACTER] knob in the counterclockwise direction and the disc table starts to rotate in the same direction. Check that the waveform at this time is the same as that in step 4. If larger by a considerable extent, rotate the [DISC/CHARACTER] knob in the clockwise direction and the disc table starts to rotate in the same direction. Repeat from step 4. 6. Rotate RV501 of the MAIN board and adjust so that the H and L portions of the D.S waveform become the same.
1. Connect the oscilloscope to Pins 1, 2, and 3 of TP1 of the MAIN board. 2. Check that no discs are loaded in the unit. 3. With the power ON, while pressing the [GROUP FILE] and [MEGA CTRL] buttons, press the I/1 button. Rotate the [DISC/ CHARCTER] knob, select �Table Rotation� and press the knob. The disc table starts to rotate in the clockwise direction. 4. Loosen the fixing screw, move the mounting board (SENSOR), and secure the mounting board (SENSOR) at the point the H portion of the P.T waveform comes the center of the H portion of the D.S waveform.
