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!
