    Hi,

    I'm restoring a PSU from a Mac IIsi, have found replacement caps for most, bar a 35V 56uF capacitor which I think acts as a bypass capacitor. All the caps have leaked an absolute mess, but I'll press on and see if a recap and deep PCB clean does the trick.

    Locally, there aren't very close matches for 35V 56uF. I have on hand some good quality 50V 47uF caps (and also found a 50V 10uF part); in parallel would these suit - or just leave the one 50V 47uF noting what might be "good enough" +/- 10% tolerance?

    Thanks

    JB

    What type of capacitor is it , if an electrolytic then 47uF should be ok.
    The most important rating can be the internal resistance if its a switch mode power supply not the capacitance.

    Yes, electrolytic. Thanks for confirming.

    The more I read about soldering capacitors in parallel it appears a poor solution.
