High-quality scanning. Detailed description. Recommend for all technician. A+++
;
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.

Great product. Recieved it fast...exactly as advertised.
SECTION 4 ELECTRICAL ADJUSTMENTS
BASE UNIT SECTION
Note: � Apply 9V dc from regurated DC power supply. � Perform the adjustment at T3CH (28CH : 49.910 MHz) as a rule. � Set to base unit manual test mode. (Refer to page 7.) � Switch position : S302 (DIAL MODE) : P (pulse) TX SECTION ADJUSTMENT � The electrolytic capacitor (10 µF/10 V) connected TP23 (DET OUT) to TP19 (GND). (Only TX section adjustment) TX VT Adjustment Setting :
TP2 TP3 (RX GND) Carrier frequency : 49.910 MHz Modulation Deviation Output level : 1 kHz : FM 3 kHz : 60 dBµV (1 mV) (EMF)
RX SECTION ADJUSTMENT RX LEVEL Adjustment Note: � Perform the adjustment at T3CH (28CH : 49.910 MHz) as a rule. Setting :
FM RF signal generator
digital voltmeter
level meter
+ �
TP6 (TX VT) TP19 (GND)
+ �
Procedure : 1. The digital voltmeter connected TP6 (TX VT) to TP19 (GND). 2. Adjust the L52 for 2.2 ± 0.05 V reading on the digital voltmeter. RX VT Adjustment Setting :
digital voltmeter
TP105 TP104 600 �
PBX tester or DC 48V F.B.
+ �
TP5 (RX VT) TP3 (RX GND)
Procedure : 1. Adjust the FL101 for the maximam reading on the level meter. Also check that the output level is the specified values. Specified Value : �1.4 to �9.6 dBV RSSI Hi Adjustment Note: � Perform the adjustment at T3CH (28CH : 49.910 MHz) as a rule. Setting :
AF oscillator FM RF signal generator
Procedure : 1. The digital voltmeter connected TP5 (RX VT) to TP3 (RX GND). 2. Adjust the L101 for 2.4 ± 0.05 V reading on the digital voltmeter.
Output: 20 Hz
TP2 TP3 (RX GND) Carrier frequency : 49.910 MHz Modulation : 20 Hz (EXT) Deviation : AM 50% Output level : 17 dBµV (7.1 µV) (EMF)
oscilloscope (DC range)
+ �
TP9 (SIG OUT) TP19 (GND)
Procedure : 1. Use the oscilloscope to confirm the FM RF signal generator input (AF) signal waveform and RSSI signal, and use the RV101 so that they are synchronized (duty is synchronized).
RSSI output waveform 0V Adjust so that they synchronize at 0 V. RSSI WAVEFORM AF oscillator EXT signal 20 Hz
Adjustment Location : base main board (See page 13.)
