Re: Medion MD41527 PS b/d hissing/crackling noise
In my quest to beat this thing I am looking at replacing the Optocouplers marked P421F just out of curiosity. Once I come across a Viper that will be next on my list to change.
Can these be replaced with either a Cosmo 1010 817 or a PC123?
The PC123 looks like a good match comparing the spec sheets unless I'm missing something.
Thanks
