Broken CRT wire repair

Andy is on the right track. I have used silver filled exoxy to repair broken wires on a 15GP22 CRT. They were low current signal pins. Don'k know how much luck you would have with fialment wires, but it might be worth a try. Not as scary as filing glass down and attempting to solder. And if it does not work, you can remove it and try the other approach. The only down side: the silver filled epoxy is expensive and does not haave a long shelf life.

The forst photo shows the CRT with the 4 pins broken off flush with the glass (pins 13, 17, 18 and 19). The idea is to build a little cup around each broken off wire into which an extension wire will be inserted and then back filled with the silver epoxy, as illustrated in the second and thrid photos. Very flexible super-fine multi strnded wire was used for the extensions, so the wires would not trnasfer any mechanical loads from the CRT base once the base was installed.
