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.
ADJUSTMENT
1. Clock Adjustment Settings : � Test point : TP2 (OSC) � Adjustment location : L901 Method : Set to AM 530kHz <YU,YL,AHA>,AM 531kHz <AK,AEZ> and adjust L901 so that the test point becomes 1.0MHz ± 1kHz. 2. AM VT Check Settings : � Test point : TP1 (VT) Method : Set to AM 530kHz <YU,YL,AHA>,AM 531kHz <AK,AEZ> and check that the test point is 1.0V ± 0.5V. Then set to AM 1600kHz <YU,YL,AHA>,AM 1602kHz <AK,AEZ> and check that the test point is 6.5V ± 1.0V. 3. AM Tracking Adjustment Settings : � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : ANT801 (Bar Antenna) ....... 600kHz <YU,YL,AHA> ANT801 (Bar Antenna) ............... 603kHz <AK,AEZ> TC801 ................................ 1400kHz <YU,YL,AHA> TC801 ........................................1404kHz <AK,AEZ> *Repeat this adjustment a few times until the wave shap has the maximum amplitude. 4. AM IF Adjustment Settings : � Test point : TP8 (Lch), TP9 (Rch) � Adjustment location : L806 ................................................................ 450kHz 5. FM VT Adjustment. Settings : � Test point : TP1 (VT) � Adjustment location : L805 Method : Set to FM 108.0MHz and adjust L805 so that the test point becomes 7.0V ± 0.2V. Then set to FM 87.5MHz and check that the test point is 1.5V ± 0.1V. 6. FM Tracking Adjustment Settings : � Test point : TP3 (FM-IF) � Adjustment location : L804 Method : Set to FM 98.0MHz and adjust L804 so that the test point is maximum and distortion is minimum. 7. FM Separation Check Settings : � Test point : PHONES (J701) � Volume : MAX � Input level : 60dB, 1kHz Method : Set to FM 98.0MHz and check that the test point is more than 17dB. 8. Mono Distortion Check Settings : � Test point : PHONES (J701) � Volume : MAX � Input level : 60dB, 1kHz Method : Set to FM 98.0MHz and check that the distortion at the test point is less than 3.0%.
