Hi all, I have a karaoke amplifier with the capacitor blown on the switch. That looks to be a 103 2KV high voltage AC ceramic capacitor ( Link ). Would it be fine to replace it with a "10nF 250VAC Metallised Polypropylene X3 Capacitor" ( Link Here ). Thanks

 

Hi, I would say higher voltage then 250, it may not lost that long with the arcing going on in the switch. You can see the original is 2KV probably DC so about 1KV AC.

 

This capacitor is rated to be permanently connected across the mains supply so, yes, it will be a good replacement.
