Thanks. It sure is scary. I'm used to working with CRTs half that size not to mention that most of the outer surface is at 12,000 volts!

I have those dark lines to some extent on a few of my sets. They can be caused by a bad damper tube or too much horizontal drive from what I've read. I imagine there are several other components that could be off or miss-adjusted that cause them.
