What is the life span of an electrolytic capacitor?
In a 26 year-old piece of video equipment, should I replace all the
electrolytic caps with such ratings as 4.7uf @25v or just concentrate
on the high voltage ones like 10uf @ 450v.
Which ones are more prone to failure under normal use?


I looked on my repair1.htm file which has 88 vcr repair briefs,
only 5 faults concerned electrolytics. If 85 degree C caps
in screened ps then perhaps replace with 105 deg C. Otherwise
my mantra is
"If it aint broke , don't poke"
