To correct my earlier post - I know it's C4 not C6 that is the 1uf/50v

What about those big electrolytics? C2 and C11 I think...should I swap these out? They look like there in good shape.

Sorry for all the questions but I noticed on my original SE (68000) logic board, there are no surface mount caps...just the original electrolytic ones and they look original and not popped or leaking. That computers runs perfectly. Never a problem. So the question is do all electrolytics go bad eventually or do some last indefinatley?
