Hi and Happy New Year!!

I've got as a Christmas present an Apple Profile, the seller told me that it was in perfect working condition but... when I powered it on I got my real present... a RIFA stinky smoke bomb 😓.

I am going to start the restoration of the Profile and I am going to replace the two 0,1uF RIFA capacitors, but I am not sure if I need to replace the other four film capacitors:
1 x 0,1uF
2 x 0,22uF 100v
1 x 0,022uF 100v

And if so, what are the best replacements for these capacitors?

Thanks for your help!
José Luis

All those filter caps gotta go. They aren't actually RIFA brand from the look of it, but they're the same type and will blow.

Thank you! I will try to find replacements for them. I suppose that metallized poliester will be an option.

Trying to fix up a Profile Power Supply as well. Looks like one of the RIFA caps blew on this one (as did the fuse). What did you use to replace those safety caps? I couldn't tell what kind of caps would be best to replace them, but want to tackle them all while I have it apart.
