If the capacitor is rated for AC, (330VAC) then it shouldn't have a
polarity marked, should it? Maybe we get confused because AC rated
capacitors CAN be used on DC (with a voltage rating about 3x the AC
rated voltage.) But if it's AC rated, then using it on AC is what's
expected! Am I missing something?
