    Amiga 500 PSU

    Hello!

    So i am replacing all the caps in an old Amiga 500 PSU.

    Now, im not quite sure about the main 400v 47uF cap.

    The one my supplier had that was exact in the values, and closest in dimension is a Panasonic EEUEE2G470S
    Now, this one have very thin legs, and the original have quite "beefy" Please see this image:

    Can i still use it, you think?

      the original is not "radial", it's "10mm snap-in" type.

        Thank you! No wonder why I didn't find the right “form factor” hehe

          You sure it's bad? Marcon made good caps AFAIK, although after so many years they could fail, sure. Still, input caps with ordinary PFC-less circuits usually last long. You can use pretty much anything if it fits physically, it just filters the rectified grid voltage.

            Actually, the PSU is fully functional.
            However I plan to use it quite a bit more now so this is a precautionary measure

            All the caps actually read good ESR so that's quite surprising after all these years.

            But I hope this will prolong the life of the psu

              the usual problem in amiga psu's is cracked soldering to the parts on the heatsink.

                yes.
                but the caps are very old now.
                i would replace them while i was in there.
                primary use whatever.

                  don't forget the "exploding rifa" across-the-line cap!
                  "pokemon go... to hell!"

                  EOL it...
