Those are the massive ones sittng horizontally on
the PCB, right?
That is correct.
there's a smaller can-type electrolytic on the
output side.
Yes on the 7441 there are two small axial style electrolytic that stand
vertically on the PCB. These are small and cheap enough here to just
replace so I think I will do that.
I am more used to (older, 25A) H744. I thouther there was another largish
can in that one on the output side. I will have to look at the prints.
Based on your suggestion that 22000uf 50V would likely
be OK I wonder if
the following part might be an alternative:
