re capping

I hear the phrase 'recapping'. when do you know when you should 're cap' an amplifier? I have a McIntosh mc602 amp that sounds fine to me. I also have a McIntosh mx132 that works ok for me. I also have a bose 901 series 2 active equalizer that seems to work ok. the 'red' on light kinda flashes now and then. if my system sounds ok, should I worry about my units?

Hey, same thing happened to the Quonset hut full of Volkswagen size non oil-filled capacitors the US Navy replaced oil-filled capacitors with on that secret communications project back in the 80s. They exploded. Of course the millions watts might have had something to do with it.  Lesson learned. 🤠

Sorry you didn’t get the jest! A social comment by me on the societal status of "facts" and "truth". They are, as considered by the more progressive citizens, as fluid concepts. The many shades of gray!😮

Electrolyte is simply drying out.  Each 10degC temperature increase shortens the life of capacitor by factor of two.  Capacitor rated  60,000 hours at 25degC wil only last 30,000 hours at 35degC, 15,000 hours at 45degC  etc.  This can be found on many datasheets.
