About the Y capacitor, what voltage will fall across it when the prime is at 240V AC? From the picture it looks like a low-cost ceramic disc cap instead of a metalized film type. Ceramic caps tend to short when failed, while metalized film ones have "self-curing" feature that end in open when failed. Is this a safety concern?
