That looks really nice! Mine has a very small purity problem in the lower right corner, and I think it might be due to the tube needing to be degaussed, but I'll try the magnet again. The rest of the screen is just right.
BTW, I notice that your 4 also doesn't fill the screen all the time at the left side. Interesting; mine does the same thing. If I increase the line volts to 120 I can get a full pic. These things have notoriously poor voltage regulation, so maybe that's one of the problems. Don't want to screw around with the width circuit again yet.
