I've read a few about re-capping... is that recommended for specific models or all models? I was under the impression that unless there is bulging or leaking, caps are fine?
SMD Electrolytic caps in A600/A1200/A4000/CD32 are the problem unfortunately. They leak, you can spot the leak by the dull finish on their solder joints. I suppose they could just dry out as well. In any case, those types of capacitors should be changed now if not already done so (they're not supposed to last above a few years anyway).
Lot's of Amiga's are still working fine with the original caps still in place (after 20 years) but it's very wise to check for leakage as any leakage can quite easily damage your board and even write the board off.
