I've still got my C4 preamp in a million pieces and struggling to find the time to get it finished, but in the meantime I found a nice C-85 preamp for cheap with only a few little issues, mostly cosmetic or just in need of a minor tweek and blast of Deoxit.
But one of the larger caps is swollen and I'd like to swap it out, but I'm confused...
I have 2 x Nippon 35v 4700uf 85degC caps like this

(note the nice bulging top here)

and 2 x Elna 35v 4700uf 85degC caps like this

One of each is bulging, so I'll change all 4 out.
They all have the same 4 leads. 2 of which seem to be dummy/mounting leads which go nowhere on the board, so I guess I can swap out for equivalent 2 lead caps with the right spacing, but why are there 2 different types?
Is there any reason why I can't swap all 4 out for the same 35v 4700uf audio grade cap with the right lead spacing or am I missing something here?
thanks in advance,
James
