I was able to get it centered, and can now make the vertical linearity look great and still fill the screen. It really made a big difference. The set is very watchable right now.

The sound is relatively decent -- as good as I could get without going through a full IF alignment, but the ratio detector has quite a low SNR. I'm not sure how 'quiet' I should be able to get it. Its very listenable as is, but I don't really know what all I should expect out of it. I'll try to post some new pictures and maybe a test pattern if I can find an easy way to get it from PC to NTSC.

Actually, that's not a screw adjustment. That tightens the lever when finnished. The lever does all the adjusting. You didn't need to pry it. Merely loosen the screw...
