Replaced the horizontal out and the damper tube, got a raster now, a nice horizontal line, until my vertical out tube arrives.. Looks like this thing is going to run without any maintenance..

In your pictures, I can see a RMA banded Sprague on the width control. Those babies have not been made for 50 years and I can guarantee any surviving ones will be leaking.
I'd personally suggest you pull the chassis and check caps for leakage, as something roasted those tubes and you don't want to roast your new ones. My first suspect would be that the grid coupling capacitor to the vertical output is leaking and cause the output tube to pull too much current and that took out the damper and horiz output.
If any tube plates - rectifier, horiz output or vertical output, start to glow red, kill the power immediately and find out why.
