Hello, I have this arcade power supply that I'd like to recap for maximum reliability and lifetime since I have found some Capxon and Jamicon capacitors:
I have another PSU (same model) that uses Chemi-con KY instead of Capxon GL, and since Panasonic FC are very similar and more easily available I plan to use those for this PSU. Alternatives I plan to use:
Panasonic NHG 105ºC has less ripple current than Capxon GS 85ºC, since they are general purpose would that be acceptable? I can't find 105ºC caps with the same or a bit more ripple current. Any better alternative? same with Capxon KM replacement.
It also has some Samxon that I suppose are fine, but I'm open to replace them for better alternatives. Since my power line is 220V I think replacing them for 450V or so would be a nice upgrade. Since they seem to be filters would low esr be acceptable for this? I can't find GP with these specs.
There is also a Samxon KM 2.2uF 50V (ripple 20) that I could replace with a Rubycon PX 2.2uF 50V (ripple 20 too).
Does this sound ok?
