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.
In case of warming up of more than 2 hours under a condition that the large anode current is running through the projection tube so that for example the all-white pattern appears, adjust to obtain the sharpest focus while observing the whole screen like in the RED case. 11. Use the focus VR of �G� of the focus pack in order to adjust the electric focus in the middle section of the screen to its sharpest level. Note: Normally the most clearly visible point of the scanning line is the sharpest point of the Green focus, however as the characteristics vary depending on the projection tube, the sharpest focus points of the vertical and horizontal lines may not match each other, thus when you turn the focus VR, if the picture tends to be tremendously unstable (rolls horizontally or vertically), adjust the balance of the vertical and horizontal lines to its best position. 12. Check the GREEN focus of the whole screen and if necessary repeat steps 10 and 11. 13. Fix the GREEN lens by tightening up its fixing screws. 14. Expose only BLUE by covering the RED and GREEN lenses with caps. 15. Loosen the BLUE lens fixing screws (refer to Fig. a), and adjust the BLUE lens focus while observing the middle and peripheral screen sections. 16. Use the focus VR of �B� of the focus pack in order to adjust the focus in the middle section of the screen to its sharpest level. (The point of the Blue focus becomes sharpest when the brightness level of BLUE is lowest, the cross-hatch is clearly visible.) 17. Check the BLUE focus of the whole screen and if necessary repeat steps 15 and 16. 18. Fix the BLUE lens by tightening its fixing screws.
TILT ADJUSTMENT Rotate R, G, B deflection yoke so that picture becomes horizon, then fasten screw. CENTERING ADJUSTMENT 1. Stretch threads towards the center of the screen (top and bottom, left and right).
2.
Enter to the user's Convergence Adjustment Mode from the menu.
3. 4. 5. 6. 7. 8.
Adjust G centering magnet so that the cross pattern center comes to screen center. Perform HEIGHT adjustment . (See page 14.) Perform VERT. LINEARITY adjustment. (See page 14.) Perform WIDTH adjustment. (See page 14.) Check whole quality of green line. Adjust R, B centering magnet so that the cross pattern center comes to screen center.
