Good day everyone.

I run a small time computer repair shop where I also repair consoles and other basic electronics.
The other day a regular client of mine came to my shop with his Yamaha M-50 receiver, asking if I could help out finding a replacement for a safety capacitor that had blown in his receiver and help replace it for him. Thing is, the safety capacitor that has blown is a Rifa safety capacitor which, from what I've seen, tends to burst with quite a bit of force. This time the damage was minimal and contained to the cap. itself with a bit of spilled electrolytes to clean up but next time it might cause more damage. For this reason I don't want to replace it with the exact same capacitor if I can avoid it.

Seeing as audio is not my strong point, I would like to ask of you kind folks if you could help me out with suggesting a different brand safety capacitor to replace the original one with.
here are pictures of all sides of the safety capacitor:

Any X2 class capacitor should suffice.
275Vac - 0.1μF or similar.
Providing it was across the mains input.

Thank you for the info.
Any brand/series you recommend? I want to make sure the audio quality remains top notch.
Rick.

I’m no audiophile and don’t believe the hype in £1000 RCA cables.
Having said that, MKP are mentioned a lot on audio forums.
Have a look here.
Your original Rifa are renown for problems. Yours is a 0.22μF so get the same capacitance if you can.

none of the good known brands will have any effect on the audio quality
TBH ... no brand will have any effect
and HEY, so much for ya RIFA brand ... it blew itself apart !! ;) ;)

would this one be a good option? its the only x2 class .22pF film capacitor I could find that has the closest match to the lead spacing of the original rifa one. (+/- 20mm)

Hi and sorry for no reply. My internet was down.
Yes, that’s fine. But I’m sure that you’ve already got it sorted by now.
