Thanks for all the suggestions. I've pulled the
PCB out and the
positive terminals at both ends of each of the three capacitors are
directly connected to one another by a trace on the underside of the
PCB. Given this, is there any reason I shouldn't replace these with a
more conventional 1300uF 75V electrolytic?
My only conern would be that such a replacement might have a higher
inductance amd that might matter. I suspect there are
conventional-looking capacitors that would work, though.
