Worked like a charm. Only a little deviation from the original positions. A more distance from original adjustment means weak CRT or some kind of issue in the circuits.

I will give this a try as testing the CRT puts it as being good and I don't want to push it harder than it should be so I lasts as long as possible.

So when I do this I should turn the brightness control down to a very low level, but the image should still be visible for adjusting. Contrast matter? Then once I adjust for a good grayscale, I turn up the brightness to a normal level and readjust the guns.
