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.

Manuals were delivered promptly and were correct as advertised. No issues with the download link which was provided promptly after everything was processed. Very pleasant experience

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 17.) 4 Check and adjust the video search rewind back tension. (See page 17.) 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 20 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.

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. Play back 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.
