This is best done with the set sitting in front of a mirror so you can see the progress.
After purity is done, set the convergence. Turn all three screens down. Flip the service switch. Turn up the red until you can just see a faint red line on the screen. Then turn up the green until the line becomes amber. If the lines don't converge don't worry about it, just set the green for as equal brightness as the red.
Now flip the service switch back to normal. Get a crosshatch pattern up on the screen. Now adjust the red and green static magnets on the CRT to converge the red and green on top of each other at the center. The red and green move diagonally, so it might be a bit tricky at first. Just look in the mirror to check your progress.
Once that has been done, flip it back into service mode and you should see an amber line again. turn up the blue until the line becomes white. If the blue line doesn't line up just make it the same brightness. switch back into normal mode again. With the cross hatch pattern up, converge the blue on top of the red and green. The blue static magnet on the CRT moves the blue up and down. The blue lateral magnet is on the assembly where the purity rings were.
Once the static convergence has been completed, touch up the grayscale by adjusting the screens for the perfect black and white picture. Then adjust the drives for the correct whites. Afterwards you can really get it looking good by performing the dynamic convergence setup.
Great looking set. Welcome aboard!

OK, I degaussed it. I feel like an idiot asking, but what are the purity rings? Can you point that out from my picture #2? What is the deflection yoke in the same picture. Also, I didn't see a service switch anywhere on the set.
Sorry for asking, I had a really good repair guy in NY many years ago, someone named Vaughn, when I bought my first sets and he always set them up. I am no where near as technical as many on this board but I usually can learn if I get instructions.
Thanks to all for their assistance.
