What about the smaller cap under the diode or is it just that same
one?

It's ok. I re-opened 2 of the 5 power supplies and tested the 470uf
10v smaller cap. They're fine. The output circuit is a PI section,
with the 1000uF 16v cap at the input, a choke, and then the 470uF 10v
cap. The 1000uF gets all the ripple current, which is probably what
killed it.
