Thanks for the nice comments! This one turned out to be pretty easy to resurrect. I wish they were all this easy! (Or maybe not, since trouble shooting is half the fun
) Since I took the photos, I degaussed the CRT which cleared up a minor purity issue. I haven't touched the convergence and I'm inclined not to since it's really pretty good. I am now running it on a variac set to 117V which is the input voltage specified by RCA.
