as far as were to hook up, I would pull the CRT socket back a tad and use the clip on style scope probe.

Thing is, the second picture is full contrast AND full brightness w/massive blooming. It's definitely being overdriven. If you try to watch program content, it is way too bright and washed out. The jail bars are the most noticeable with normal levels of brightness and contrast.
I usually bring up the contrast to the point of blooming and then back it off. I then keep backing it off until the level is right for the viewing environment. I then adjust brightness up until I get decent shading in the dark areas of the picture. Sometimes I have to go back and forth between the two controls to get it right. In no way am I driving it too hard with those controls and the G2 voltages are within range.
Tomorrow will be my day for checking the cathodes, G1 and G2s.
