Actually the high voltage anode lead is very well insulated; if it isn't any more, you'll be sure to notice it quickly (smell, arcing noises and lights, TV stops working eventually). However, in a typical CRT drive circuit you still may find somewhat high-power 100-200 V DC supplies (for deflection drivers and also what powers the LOPT) and low power ~1-3 kV supplies for focus control and such.
