That is what it looks like exactly..like a reflection off the bell.
If it's caused by incorrect phase adjustment it'll be a stretched out image. But it's not always easy to tell if it's that. I believe the black band on the right should be about 1/4" wide if the phase is right.
How can I adjust the phase?
Sometimes I think the images of the people look a little elongated..
So maybe I should try this adjustment if you can elaborate. And yes the black band is about 1/4" wide..but what do you mean by if the phase is right?

It sounds the phase is right. I'll have to scan the procedure, it's fairly long, word-wise.
The horizontal linearity and drive might need adjusting also. I'll scan that too.
