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.
;
Very good conversation, Pretty fast Service, wood do it again,
Have paid by Paypal, so i got the Service Manual online after 15 Min.
Very helpfully.
Greeting from Germany,

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.
DV-515, DV-414
IMPORTANT THIS PIONNER APPARATUS CONTAINS LASER OF CLASS 1. SERVICING OPERATION OF THE APPARATUS SHOULD BE DONE BY A SPECIALLY INSTRUCTED PERSON.
Additional Laser Caution 1. Inside detection switch (S201 on the SMEB assy) and loadingstatus detection switch (S301 on the LOSB assy) are detected by the microprocessor (IC501 in the DVDM assy). � To permit the laser diode to oscillate, it is required to set the inside detection switch for the inside position (S201 : ON) and to set the loading-status detection switch for the clamp position (the center terminal of S301 is shorted to +5V). The 650 nm laser diode for DVD oscillation will continue if pin 19 of IC101 is shorted to +5V (fault condition) in the DVDM assy. The 780 nm laser diode for CD oscillates if pin 20 of IC101 is shorted to +5V in the DVDM assy. In the test mode � , the laser diode oscillates when microprocessor detects a PLAY signal, or when the PLAY key is pressed (S113 ON in the FLKB assy), with the above requirements satisfied. 2. When the cover is open, close viewing through the objective lens with the naked eye will cause exposure to the laser beam. � : Refer to the service guide RRV2004.
LASER DIODE CHARACTERISTICS FOR DVD : MAXIMUM OUTPUT POWER : 7 mw WAVELENGTH : 650 nm FOR CD : MAXIMUM OUTPUT POWER : 5mW WAVELENGTH : 780 � 785 nm
