That CRT tester has to have electronic components in it, right? From the 60's?? How likely is it to actually work the way it's supposed to? Our CRTs are half that old or less, and they're failing due to old caps, resistors, etc.

Ahh ha, you didn't watch the whole video did you? He actually lost a capacitor on the first re-juv' try. He swapped in a different value. Many people in the comments mentioned the fact that the capacitor changed value would make the medium re-juv' setting like the 'high' setting.

All in all though it made that little CRT work again. Hope he does a follow up video in a few months to see how it's doing.
Just as an aside. The last time I used an apple product it was one of those. Also use to game on an Apple ][E. at school in the 80's and 90's
