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!
CD SECTION
Note: 1. CD Block is basically constructed to operate without adjustment. Therefore, check each item in order given. 2. 3. 4. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated. Use an oscilloscope with more than 10M� impedance. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. Adjust the focus bias adjustment when optical block is replaced.

Focus Gain Adjustment (VR02) This gain has a margin, so even if it is slightly off. There is no problem. Therfore, do not perform this adjusment. Please note that it should be fixed to mechanical center position when you moved and do not know original position.
