The round color crt is vary fussy when it comes to magnetic fields in and around the room. Every time I move a set it will change the purity and convergence and I have to realign the crt. I have found when you point the neck of the crt to the south and the screen north [ or neck north, screen south } when doing a alignment it will be easier to get purity and convergence right, But not perfect. {The blue vert lines are the ones I have the most problems with.} Put the set were you are going to watch it, Demagnetize the crt and set. Do purity and center convergence. Then cut off the blue gun {turn down blue screen and drive} and converge the red and green first. Then converge the blue to the red and green. Reeferman is right, You may have play with the set to get the experience. If you get lost , Take a break for a few days and then attack at it again.
