I was in the process of recapping my SM3540 since one capacitor had already failed.
It was there when I found a cap with 3 legs and I'm not sure if I can just replace it with a modern counterpart. Two of the legs are connected to the minus rail, so its job is to increase current handling? It is situated right on the output board.
Type: 674D 820µF 50V DC
I did not find anything to be special about this thing on the internet or am I missing something?
I would go ahead an replace it with a normal electrolytic cap 820µF/50V/105°C.
Maybe somebody can prove me wrong:)
