Don't see a line on normal pictures, but something is bending the horizontal scan lines over on the left-hand side of the picture. It's not bent all the way top to bottom, just at certain points in the picture. Moving the hold all the way to the right seems to help minimize the horizontal bending. I'm not sure if the two symptoms are related?

With the RCA Synchroguide horizontal hold setting, I generally set the horizontal frequency (transformer core adjustment) so that with the full right setting of the front control it is on the verge of losing horizontal sync. At this point the horizontal oscillator is most firmly locked
The reason the white bar disappears when turning the knob and the video to the right is because the retrace is starting earlier hence the left portion of the video (vertical bar) moves to the left side of the raster where it belongs. This is further indication of too slow retrace.
Have you changed the capacitors in the horizontal sweep section? If so, recheck the values. If a capacitor is too large in value, it conceivably could reduce the resonant frequency of the flyback system, leading to too slow a retrace.
