Repairing a damage CRT/tube base

[danrulz98]

According to the Milliput website, their product stands up to 130 degrees C.

I can swing by the hardware store tomorrow and check out what the more generic stuff stands up to.

Hmm. I do know that a 6V6 I used super glue on broke down after a few days. That tube ran pretty darn hot. Over 130C I bet.

Anyone know the nominal operating temp of a CRT base of this type ?

130 degrees Centigrade is way more than the neck would ever experience. That's beyond the boiling point of water. I've used an IR thermometer (with tungsten filter to reduce the effects of the filaments temp) on CRT necks and found the temps to be about 140 - 180 degrees 60-84 degrees Celcius (~140 - 180 degrees Fahrenheit). That's probably why the Military used RTV rubber - withstands up to 225 degrees Celcius.
