 ;
OEM manual provided all schematics, board layouts and component specs necessary to facilitate unit maintenance. All pages were clear and readable.
;
Good condition and quality. Hard to find anywhere in Internet, only on this site.
 ;
Exactly what I needed to be able to bring the amp back to life... will come back to this site the next time I need schematics.
;
Information was accurate and very helpful.
However the continuity made it a little difficult to follow from one page to the next.
;
Very very good as usual very trustable site. Perfect!!!!!!

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: The PURITY/CONVERGENCE MAGNET assembly and rubber wedges need mechanical positioning. Refer to figure 1. 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)
SPECIFIC INFORMATIONS GENERAL ADJUSTMENTS
COLOR PURITY ADJUSTMENT NOTE : Before attempting any purity adjustments, the receiver should be operated for at least fifteen minutes. 1. Demagnetize the picture tube and cabinet using a degaussing coil. 2. Set the brightness and contrast to maximum. 3. Use a green raster from among the built-in test signals. 4. Loosen the clamp screw holding the yoke and slide the yoke backward or forward to provide vertical green belt (zone) in the picture screen.
5. Remove the Rubber Wedges. 6. Rotate and spread the tabs of the purity magnet (See figure 2.) around the neck of the picture tube until the green belt is in the center of the screen. At the same time, enter the raster vertically. 7. Slowly move the yoke 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.
