Both of my 6GU7's heaters light up, and it appears the aforementioned connection has seen a reflow already. I tried wiggling them around a little, and nothing changes at all.
I also noticed there is a fair amount of arcing out of the top of plastic cup on top of the fly back box. The wire to anode goes in though there, as well as two others. I'm going to need to see what that's about. I'm sure that'll be worse once I get the HV back up.
The tubes are largely original, almost all RCA. I'm hoping I just have a flat tube. I'll add the 6GU7's to the check list.
