Quoted from NovaCade:If you are not familiar with CRT's, be super careful before you decide to do anything. The voltage stored in the flybacks can send a grown man across a room.
This bears repeating! The chassis has plenty of capacitance to ruin your day, but so does the anode itself!
The worst shock I think I ever received was due to contacting the anode connection on a 27" tube that had been removed from the chassis for well over an hour; I ever so lightly brushed against it with my wedding band as I got into position to lift the tube, and I could literally feel the current travel up my arm, into my shoulder, and well down my torso before I broke contact (a fraction of a second, but that's all it took). Much more intense than grabbing a spark plug, and in addition to the direct pain of the shock my left hand was rendered clumsy and "spastic" for a couple of days following.
