What value fuse is in the holder on the rear chassis? One would expect that fuse to go open if B+ is pulling excess current. You mentioned you don't have Sams 110, by any chance do you have Sams 101, folder 5?

OK so a little update, I was able to get the broken terminals in the video amp tube socket replaced with some terminals from a parts tube socket from a junk single tube suitcase record player, and I powered it up and the 5U4G tube is still arcing even with all of the power supply caps replaced.
Although I did think of something that could be causing my issues still,
there is an oddball dry electrolyitic capacitor in the power supply that I didn't bother replacing because it was a Dry Electrolytic and usually with my experience those Dry Electrolytics rarely fail.
Plus its an oddball value that I've never seen before, not even in modern TV sets, its a 500 MFD 5 VDC Dry Electrolytic Capacitor that is tied into the power supply chain, and maybe in this case that Dry Electrolytic did short out and that's whats causing my Rectifier tube to arc inside.
Does that sound like it could be a possibility?
