It's complete and helpful manual with good quality of scan. Thanks very much.

The service was quick and simple, finding the service manual easy and it appears to be the original with colour schematics. It contained the info I was after and so sorted the problem.
I have copied it to CD and attached the envelope to the inside back cover of the owners manual. Good manual and excelent service. Robin Wood, Wood Electronics, New Zealand.

4.7.8 PURITY AND CONVERGENCE PURITY ADJUSTMENT (1) Demagnetize CRT with the demagnetizer. (2) Loosen the retainer screw of the deflection yoke. (3) Remove the wedges. (4) Input a green raster signal from the signal generator, and turn the screen to green raster. (5) Move the deflection yoke backward. (6) Bring the long lug of the purity magnets on the short lug and position them horizontally. (Fig.2) (7) Adjust the gap between two lugs so that the GREEN RASTER will come into the center of the screen. (Fig.3) (8) Move the deflection yoke forward, and fix the position of the deflection yoke so that the whole screen will become green. (9) Insert the wedge to the top side of the deflection yoke so that it will not move. (10) Input a crosshatch signal. (11) Verify that the screen is horizontal. (12) Input red and blue raster signals, and make sure that purity is properly adjusted.
