My CTC-5 has this dot size issue, with red being larger. I was concerned about the crt, though all 3 guns test good. Somebody is going to tell us what it means.
You can find replacement controls. For the DuMont I swapped them off of a used RCA board. They are not all the same value so you need to get the correct ones. I bet Moyers carries just what you need.

Red spot size will be somewhat larger in tubes where the red needs more drive than the green and blue, especially on strong white dots. I would expect the red spot gets more reasonable when you turn down the contrast. If the effect is not bad on ordinary pictures (as opposed to hard-driven dot pattern), I wouldn't worry about it.
