I changed R741 to 1.2meg, the neon lights to a 220k 1W resistor, and R701 to 4.7meg. This did fix the problem with the color not coming up right away. But now the color control goes too high, too much color if it is set much over "2-3" even on a weak signal (Before I set the color nearly right in the middle between 4 and 5). And the brightness control goes higher too now, and at about 2/3 of the way up the picture starts shrinking horizontally on the left and otherwise blooming out, at 3/4 it just blooms, and disappears at higher brightness - Normal brightness is at about 1/4 - 1/3 of the way up. (Before it was at normal brightness at about 1/2 - 2/3 up, and began to shrink horizontally and then bloom at over 3/4 up, it never got so high it disappeared.)

I tried 5.6meg instead of 4.7 for R701, (I even tried 10meg), but it didn't really make a difference. Setting the color control low doesn't really bother me, but I'd like to do something about having the picture blooming so much it goes away entirely at top brightness. I suppose I should check the HV first, but I don't yet have an HV probe.

I'm going to be moving in about a month, so I have to quit working on my sets and start figuring out how to pack up all my stuff. (Which seems like a completely impossible task.) I might bolt the chassis back in and leave this set as is until I'm totally relocated.
