    Hello there 🙂 I will start by replacing the big can metal capacitor 3x1500uf that is in parallel so 4500uf will be ok if I find one, or else 3×1500 new capacitors in parallel.

    The question is (looking at the schematic) Why back then they put 60v capacitor when the output from the transformer was / is 60v? This sounds like “in Limit’? It was a reason? Should I replace it with 100v one for more safety?

    Thank you
