Well... That looks a lot better:
Maybe this is a low hour set. Would explain why it's so clean on the inside. There's plenty of headroom left on that G2 control and the picture is super sharp.
Maybe you're right JohnCT Maybe some ham and egger screwed with the controls. I would still love to borrow a CRT tester just so I would know what condition the CRT is in, but doing a proper setup really helped.
