I have a Sencore VP301 HD sig gen. I can cut off any or all three
guns, and it has patterns that allow centering, edges,grids,black,etc.
Probably that would help. I like it because if I want to do an
electrical focus on the three tubes,I don't have to access the CRT's
to cover the two so I only see the third. I just extinguish, say, R7B,
and focus green.That's a help.
BTW this whole family are smokers.Smells like an ashtray.I'm sure the
lenses and mirror are yucky.
Thanks,
Phil
