Yes, indeed there is a big chunk of base missing and the epoxy was slopped in. I did some more work on the set and have a better picture. So, for now I'll just leave the old CRT in there.

Yes, I have a pretty good centering range with the lever. The horizontal centering is also effected by the hor. drive, hor. lock and hor. sync.

I found a few out of spec resistors in the hor. oscillator circuit and just replaced them all. That threw the oscillator off a bit so I went through the adjustment instructions in the service manual. When I finished with all that, here's what I got. The horizontal linearity isn't perfect, but overall not too bad I think.

First picture is from my Leader LCG-400, then a local low power OTA VHF transmission. Last two are from a converter box.

Not so clean topside This set came from Florida and I suspect the humid air contributed to this rust. I'm going to tackle it with some naval jelly then paint the worst areas to keep it at bay.
