Philco 46-480 Power Supply
#14

I need to resurrect this old thread of mine to ask a related question. I've never thought about it, but this just now occurred to me. For a plate bypass capacitor, such as the one shown in the below schematic, should we be using safety rated capacitors? Now that I am thinking about it, I feel that we would really prefer for a capacitor connected to the high voltage output of the transformer to fail open.

I suppose the essence of my question is, do we utilize safety capacitors in situations other than the line-to-ground line filtering capacitors connected to the AC mains in the power supply section?
