Never mind. Ancient and unreliable test equipment. Lesson learned.

Besides the generator, it never helps to lean the CRT up against a piece of test equipment with a huge 60 hz isolation transformer inside. After all the CRT is magnetically deflected.

Not to pile on but I've also seen changes in deflection setup when running sets that early on their sides....I kinda learned the hard way that if the original settings give somewhat reasonable picture with the set on its side don't try to tweak to perfection with the set on its side as the change in position relative to earths magnetic field will throw several things slightly off when turned upright....
Similarly on color sets try to have the set facing the same compass direction as you plan to store and use it in when doing scan setup and purity and convergence.

This was a major point with pre-autodegauss sets (e.g., RCA CTC-15 and prior).
