Yeh I have worked around them before and given them the room and respect deserving of something that can store enough charge and impart a high enough current to cause death, but never had any desire to explore them any further even tho i have a sound understanding of electrical principals and the basic ins and outs of a CRT. For something where there consequences of an error are painful and destructive at best, a i didnt consider a basic understanding to be sufficient to go into it with boots on lol.... CRTs are scary!
