I never could understand why some manufacturers chose to connect a line capacitor ahead of the power switch, brand Z sets, even AC/DC ones, always seemed to do this. Whenever I run into a set like this, and it's feasible to do so, I move the line capacitor to the radio side of the switch so it isn't energized unless the set is turned on. RCA sets, and Canadian G.E ones, had an electrostatic shield built into the transformer so they didn't need line capacitors. Philco seemed to like connecting two line caps between either side of the power line and the chassis so while you could switch one of them you could not switch both.
