obligatory post after my joke post about how a crt could kill you, and how it can zap you with some static with the case shut:
While working on an open CRT can be dangerous, the amount of danger involved is often overblown to the point of discouraging people from safe and sane repair and adjustment. Do not touch under the anode cap with your fingers, don’t stick your hands in the flyback, don’t touch caps and other storage spaces for energy that you’re not sure are discharged or at a safe level (the human body doesn’t need a lot of current to get hurt!)
I’ve known some fairly prolific repairers of tube equipment, and while you do get desensitized to danger the longer you do something, overall, the impression I’ve gotten is that “common sense” electrical safety is what is needed, and that scaring people further just means people are afraid to ever try. Also, people often don’t recognize there’s much more danger in many every day situations just by how much more likely it is for you to underestimate a potential danger, or for it to occur.
You will not get hurt adjusting the knobs on the other side of the tube. Just trust me. Maybe don’t copy some of my “workbench” setups, though:

Excellent points!
I recently witnessed a technical help chat wherein the dangers were not properly conveyed, and rather a blanket “just don’t” was recommended instead. After which, the person was banned from the space, and now you have someone who not only has no guidance on what the actual dangers are, but they’re now flying blind and my just go in and touch the wrong thing.
CRTs are not magic. But they are mysterious if all you’ve ever been exposed to are LCDs. So, let’s de-mystify them in your mind with one of the single best CRT experts in North America.
Each video covers something a little different, but either way, you’ll learn the thought process required to approach them and handle them safely.
