Man, you are doing this build right!
Love the K7000’s. Next to the G07’s, this monitor is very serviceable. The colour looks like a purity issue in the title screen shot. The lower right seems off to me.
Could use a degauss, but if the monitor’s degauss isn’t working well enough, a degaussing wand might do the trick. Or you can try adjusting the purity rings.
As for the bleeding greens, you might want to adjust the R G B balance pots on the neck board.
Other than that, wouldn’t hurt to throw some new caps on the chassis.
