I decided to junk the set, Mark. I was going to try a used yoke from another set, but the convergence / Purity ring assy. disintegrated in my hand. The CRT also has a little too much phospher burn marks on it, due to the prison using it as a monitor. I think the yoke was bad,...but,...at this pint I don't care. It's,......JUNK.
