I've heard a few times that electrolytic caps might be due for replacement after 20 years, lest they fail and destroy other bits with them. I've not heard that about small film caps like Wima, but could easily have missed it.
Does this same 20 year estimated life expectancy apply to power caps (cans)?
And if replacing them, which changes tp specs are not so relevant and which might have a knock-on effect (risk) on the downstream circuit components? For instance, I have 4 cans @ 10k uF 50vdc and of course am wanting to make sure the new cans will fit in the mounting brackets. So if I replace them with 10k uF 80vdc do I need to review and respec the other components? Or if I replace with 33k uF 50vdc would that make a difference to the circuit?
