A site where discontinualed schematic diagrams and back dated information can be found on discontinued radios tv's and any electronic equipment can be found. Newer manuals either Service and operating manuals. Radio amateurs should find this site a great source for ham radio equipment manuals. I will return to this site should I need information on any electrical equipment. priced easy to download in a PDF format and print pages need to undertake the repair.

SET-UP ADJUSTMENT
s The following adjustments should be made when a complete realignment is required or a new picture tube is installed. Perform the adjustments in order as follows : 1. Color Purity 2. Convergence 3. White Balance Note: 1. The PURITY/CONVERGENCE MAGNET assembly and rubber wedges need mechanical positioning. Refer to figure 1. 2. Mounting position of the purity magnet assembly should fit to same position as old one because slightly difference to the position depend on a kind of tube. * There are no adjustment of purity and convergence in some picture tube (Unified with purity magnet) COLOR PURITY ADJUSTMENT NOTE : Before attempting any purity adjustments, the receiver should be operated for at least fifteen minutes. 1. Evenly degauss the entire screen. 2. Set the CONTRAST and BRIGHTNESS Controls to the maximum. 3. Display built-in green raster using the TEST SIGNAL SELECTION function. 4. Loosen the clamp screw holding the deflection yoke (and remove the rubber Wedges). 5. Slide the yoke forward or backward to provide vertical green belt (zone) in the picture screen. 6. Rotate and spread the tabs of the purity magnet (See figure 4.) around the neck of the picture tube until the green belt is in the center of the screen. At the same time, center the raster vertically by adjusting the magnet as shown below. Figure 1. RUBBER WEDGES

7. Move the yoke slowly forward or backward until a uniform green screen is obtained. Tighten the clamp screw of the yoke temporarily. 8. Check the purity of the red and blue raster. 9. Put four wedges into the space between the picture tube and the yoke to hold the yoke in the adjusted position. (See figure 2.) Do not tilt the yoke by excessive insertion of the wedge. 10. Remove cover paper of wedge and stick wedges on the tube to fix the yoke in the adjusted position. Fix the wedges with glass cloth tapes.
