Thinking about why new CRTs snap crackle and pop: I wonder if it's because there are minute sharp points here and there inside where HV concentrates, and after a while these get burned off? I don't mean actual needles sticking out but just little bumps in the coating and/or on the tube elements. They act like tall trees for the HV lightning to strike. Got to be some reason why the tube finally settles down.
