Old Muntz TV for sale Locally to me, Should I pick it up?

[vortalexfan]

OK so I was finally able to get the chassis out of my Meck/Philharmonic TV and repopulated the chassis with known good tubes from my tube stash and plugged it in to test it out and when I turned the TV on all of the tubes including the Picture tube started glowing but then a few seconds later the 5U4G Rectifier tube for the power supply starting sparking and arcing inside so I quickly turned it off and unplugged it.

Any ideas as to what could be causing the arcing 5U4G Rectifier tube? thats the only tube in the whole TV that was arcing the rest of the tubes were working fine.

I did notice that the Power supply filter caps (which are in a cardboard can) was snapped off from its phenolic wafer that held it to the chassis (the phenolic mounting wafer that the capacitor can was mounted to itself was snapped off from the chassis not the capacitor can itself).
