The reality is that you even have to check new components to see if they are up to spec.

It depends if the capacitors dried out.  The only way you can know is if you check them.

I haven't yet had an A500 with symptoms of failing caps, but if you have the time, why not. Or like ChuckT mentioned, pull a few and check them. Just stick with the good stuff (Nichicon, Panasonic, Chemi-Con) and they should last a long time like the originals.

from what I understand, the A500/1000/2000/3000/CDTV series do not suffer the "cap" issues that the A600/1200/4000/CD32 do.  I have yet had a older Amiga have cap issues.  But I am sure there are cases.  I would say do not worry about it until you have an issue.  I know A600's are notorious for having this problem!

Perhaps the former versions use linear transformer supply and the latter use switched-mode power supply? the latter cause high ripple currents.
