Electroilytic life expectancy is ‰20 years for the older design.  Modern 
design electrolytics typically have: more C per unit volume, less leakage 
at rated WV, don't require pre-conditioning, and are generally able to 
handle higher ripple current.  I have no info on life expectancy of 
modern design units.  

cheers, John
