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.
� Method-2 (In service mode or normal operation): Check the value of current flowing in the laser diode. 1. Remove the upper cabinet. 2. Read the current printed on the label attached on the rear side of the optical pick-up.

3. Connect a digital voltmeter as shown in Fig. 2. 4. Press the � key. 5. Calculate current value by the reading of the digital voltmeter. Reading of the digital voltmeter (V) ÷ 4.7 (�) = current value (A) (Example) Reading of the digital voltmeter of 0.1645 V: 0.1645 V ÷ 4.7 � = 0.035 (A) = 35 mA 6. Check that the current value is within the following range. � Current value of the label +5 mA (25�C) �11 Variation by temperature: 0.4 mA/�C Current increases with temperature increased. Current decreases with temperature decreased. If the current is more than the range above, there is a trouble in the automatic power control circuit or the laser diode is in deterioration. If less than the range, a trouble exists in the automatic power control circuit or the optical pick-up.
