![]() Morning All,
I'm trying to repair power supply after roach did it's magic to it. There are two ceramic caps (C24 & C19) both 1nF. I found schematic but do not know what voltage they must be. Please advise if you should know. Kind regards Trevor Last edited by imboss; 04-07-2021 at 04:09 AM.. |

![]() shit.
they are in series across rectified mains. so if you have 220-240v in capetown then your looking at about 360v!!!! and you need "headspace" so each cap would need to be rated at 250v atleast IMO. |

![]() maybe 0.027?
its pretty safe to say it's o.k. given your reading and the fact that few meters will be acurate that low |
