Hi, thankyou for providing the Nordmende Globetrotter original manufacturer's repair manual. Quality is very good and sharp - the PDF file was comfortably small to download. The only question is: why did it take so long to become ready for download?? Many thanks anyway, I fixed the fault in the radio thanks to the circuit.
regards: Nick

Wow very wonderful and clear!!!! I will always trust them
SECTION 3 SET-UP ADJUSTMENTS
� � The following adjustments should be made when a complete realignment is required or a new picture tube is installed. These adjustments should be performed with rated power supply voltage unless otherwise noted. Perform the adjustments in order as follows : 1. Beam Landing 2. Convergence 3. Focus 4. White Balance Note : Test Equipment Required. 1. Color-bar/Pattern Generator 2. Degausser 3. Oscilloscope
.................................................................................................................................................................................................................................
Controls and switch should be set as follows unless otherwise noted: PICTURE control ........................................................... normal BRIGHTNESS control ................................................... normal
Preparations : � In order to reduce the influence of geomagnetism on the set's � picture tube, face it east or west. Switch on the set's power and degauss with the degausser.
Purity control
3-1. BEAM LANDING
1. Input the white raster signal with the pattern generator. Contrast Brightness normal

Fig. 3-2
2. Set the pattern generator raster signal to green. 3. Move the deflection yoke to the rear and adjust with the purity control so that the green is at the center and the blue and the red take up equally sized areas on each side. (See Figures 3-1 through 3-3.) 4. Move the deflection yoke forward and adjust so that the entire screen is green. (See Figure 3-1.) 5. Switch the raster signal to blue, then to red and verify the condition. 6. When the position of the deflection yoke has been decided, fasten the deflection yoke with the screws. 7. If the beam does not land correctly in all the corners, use a magnet to adjust it. (See Figure 3-4.) Fig. 3-3
Purity control corrects this area. Disk magnets or rotatable disk magnets correct these areas (a-d).
