[sdiy] Electrolytic capacitor life

[Dave Kendall]

Hi all.

A few years back I got many unused electro caps amongst other things 
from a clear-out of a broadcast maintenance department that was 
closing-down. I have heard that electro caps "dry out" over time. These 
particular caps are probably around 10 - 20 years old.

Are they any good? Recently I found and rejected at least one cap that 
measured well below its rated capacity.

I guess someone here has some real-life info on electro cap ageing.

Any info would be most welcome. I'd have to re-stock quite a lot of 
electros if the old ones are going to flake out......

cheers,
Dave
