Use a crosshatch pattern to adjust the static (center) convergence using the adjusters on the convergence clover (yoke). *After that put a full red raster on the set either from a pattern generator or by turning down the other screens, slide the deflection yoke back until the screen looks tie-dye, center the red blob with the purity rings, then slide the deflection yoke forward until the screen is all pure red.
After that touch up static convergence, and proceed to the dynamic convergence following the sam's procedure. It is a complex process so you may need to repeat it 2-3 times to get it optimal. If after a few tries you conclude that don't have enough control range try moving the clover around...When you have a good feel for the controls you may be able to know when/how to tweak the clover by instinct. Convergence can rarely be gotten perfect, once you have it good up to 1-3" from the edge of the screen declare victory...If you can do better give your self a cookie and a pat on the back.
* You may need to degauss the face of the CRT first. You can make a degaussing coil easily by taking one out of a newer junk CRT and fitting a power cord on to it.
