Two steps forward, one step back
Slow powerup on the variac, and while the guns were WAY off, I had a full raster and all colors!
The tuner was dirty, forgot I had to clean it, so I'm screwing with that and doing a crosshatch to get it roughed in, and then I realize that I lost color. Dammit! Or, rather, everything but green and a pinkish red. This pic doesn't show it clearly, but this is what I've got now.
Snow on the off channels is white with confetti, but that's to be expected.
Still, progress is progress
