Did they really use electrolytic caps for bypasses in the eighties? I haven't had much experience in the pre 1982 (pre-C64 that is :-) electronics but those I've seen since 1982 were using ceramics for bypasses. DC blocks - yes, I've seen those. As for replacing the aluminium electrolytic ones, I heard about tantalum ones being the best (?) replacement for the aluminium based polarised caps.
