Okay, noted. I will replace those caps as I just checked, and they do look a little old and cracked.
Also, I was under the impression that any capacitor could be replaced by one with the same capacitance, but any HIGHER voltage, as the voltage on a capacitor is only it's minimum voltage.
Correct me if I'm wrong.
I'm no expert in this so I've waited for other to reply you, but here is my understanding of this:
They can work, but if the capacitor have a lot higher voltage rating than the original part then they can have trouble forming.
Lower voltage caps also have lower ESR, important in switching power supplies.
Cheap general purpose capacitors usually have higher ESR and shorter (shelf) life (in hours) than the more expensive ones, so I always try to buy the one that lasts longer when I want to recap. I usually stick to KEMET, Nichicon or a brand type.
Just an example, the
KEMET ESY series is built for switch mode power supplies, and up to 5000 hours
