An excellent document to assist in the repair of my old personal tape player. It includes full circuit diagrams and physical layout drawings and full instructions on disassembly and fault finding.
Well worth the meagre price.

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.
