Does anyone have a DigiKey/Mouser cart or list of capacitors for the IIsi power supply? Asking before recreating the wheel...

No problem, at least maybe a place to start. Looked up the 33µf - 25V - SMT and it appears to be on order until next April… You can always go higher on the voltage rating, or look for a different brand I suppose. :-/ For the radials if some are out of stock make sure you pay attention to the size: diameter and height/length.
