Damaged CRT base

I had some time while waiting for parts to arrive, so I decided to tackle that damaged 7JP4.



I found one lead that was broken off at the glass It was for the vertical deflection so I can test it as is.


It's a runner


I had an old HP CRT from a logic analyzer with burns that's going to be sacrificed for the base. I wrapped it in a blanket and gave it a whack.


I filed down the glass around the broken lead enough so I could solder a new wire. I had it wrapped in a blanket and wore eye protection. Even so, I was very nervous while working on it.
I then attached long, thin wires to thread through the new base.


Here goes nothing!


Success
