I'm not sure how much ripple would be needed to cause a symptom like that but G2 has in the neighborhood of 3VAC present on it without any signal injection.

Well that rules out G2 and leaves only the cathode of the CRT. Try this for the heck of it- hook that 10mf electrolytic from ground to the cathode (observing polarity of course) and see if the bar remains.
One other thought- After doing the cathode shunt, try shunting G2 with the 10mf cap. Hook its neg. end to top of C116B (which carries smoothest B+) and the positive end to G2. This will effectively kill all ripple on G2,
just in case the 3VAC is sufficient to cause the bar.
