I located a 1k 15 watt resistor on another chassis, so I harvested it. Installed it and was able to pass a luma ladder no problem, so the resistor appears to have fixed the problem. Plugged the set back in, and I didn't have too much trouble making this happen.
Obviously I haven't aligned or converged it at all, but this proves that all major circuits are now functioning as advertized. I don't want to go too much farther at this point, because I need to take the CRT components apart so Bob can make anode boots for his set. He's going to copy my parts to fabricate the ones his set is missing, then we will both have complete Saratogas.
After this one is back together I will proceed with the front end alignment, chroma alignment, color AFC, and finally all the setup stuff to make a really nice picture. Should take about a month.
