Arran, that is interesting about the phosphor. I actually read about this recently in an old TV book. It mentioned that the phosphor can even degrade to the point that you can actually see into the tube from the front! Well, no matter if it is low emission or gas, the tube is tired. But, at least it is still giving service, and there is something to be said for that. Crist, that chassis is really looking nice! A little patience will pay off in locating a better tube. It took me over 30 years to find a NOS tube for one of my sets that I could afford. Mine had a line burned across the screen from a vertical sweep failure. That really wrecks an otherwise good picture! 
If I could find the place called "Somewhere", I could find "Anything"
