For film caps, this is absolutely untrue. Anything made in the last 25

You'd be amazed at how much older equipment used electroyltics.
Oh - ozone/smog hurts them as well.

I've been an electronics engineer for 35 years - I'm very familiar
with older equipment! Besides, you specifically stated that you change
*film* capacitors.
