Questions regarding broken CRT lead

[dtvmcdonald]

If it is not the heater conductive glue will work fine.

If you are afraid of overheating to solder, get some pure Indium wire off
ebay and use that as solder, using ordinary liquid flux. It melts at just the
right temperature, solders easy and won't melt with ordinary base heat. Indium
can't hurt ... its a good solder and sticks well to copper, steel, other tube pin
alloys, and ordinary solder. I've even had good luck soldering to germanium with it!

Use a small wire and glue down to the glass after soldering.

But ... I've had good luck with regular solder and a tiny tip on both CRTs and
a very rare iconoscope.
