Electrolytic capacitors are the bane of electronics.
My "other" hobby--home theater with an emphasis on audio--involves occasional replacement of electrolytic caps. The biggest improvement I made to my stereo speakers was to scrap the ~20 year old electrolytic caps in favor of similar-value film capacitors. Unlike electrolytics, film capacitors don't have a "service life" as such. Downside is that they're more-bulky, and more-expensive. Electrolytics are cheap and compact.
