The anode wire was arcing at the 1B3/flyback terminal. It had also been arcing at the 1B3 tube socket, so the socket and the anode was toast.

I did consider splittling the wafer and even did so on a bad socket, I think this would work if you could come up with a good way to put it back together, perhaps the epoxy might be worth a try.

I ended up removing a socket from a spare parts chassis I had laying around, this had 8 terminals on the bottom, after some head scratching I ended up just bending the unwanted terminals back and forth until they broke, and they broke inside the socket so nothing was sticking out. So that was an easy soloution. I desoldered everything, replaced the socket installed a new anode wire and fired it up.......No smoke, good picture and everything at the moment is working great.

Check out the pic's.

The original anode lead, in the first photo, appears to be RG-172/U coaxial cable. That may have been the cause of your original problem.
