CRT Rebuilding Video

[Electronic M]

I'm lucky to never have had a dead 21" predicta tube ignoring a necked one in a parts tandem. I did have a dead 17"...of the 8 21" predicta tubes I've had in my hands 2 needed brighteners...one was a customer set, the other was in my GE Forecaster and I recently acquired a rough holiday that had a good 6V tube ...I swapped the brighter tube into the holiday and made it work and be somewhat presentable and sold it....The forecaster looks so much better with a strong CRT now
