Hello, I have this PSU from 1994 using Chemi-con KME and Chemi-con W (custom?) capacitors and I'd like to know if it's better to recap or leave it as is. These are the capacitors used in this power supply:
Initially I've considered to recap using KMG, the indicated KME replacement, but some of them are very expensive to order here. Looking for another suitable replacement I've found that Rubycon PX have almost identical rated ripple current (some times just a bit more), but ESR is not indicated. For the Chemi-con W, since it seems to be the input filter, I've considered using Rubycon BXW or some similar capacitor rated 250V (or more if it fits?)
Since this circuit uses GP caps, does that mean that it's not very picky about ESR? if so, are the Rubycon PX or another GP caps with the same or a bit higher ripple current suitable?
