Nope. Caps are the ultimate couch potatoes: less exercise, better performance! Tubes are even better. Tubes can just lay around for years, people actually pay more, they are so well rested you can't believe!
Do caps stay "fully formed" even under minimal load? (SS)
Theoretical question. If my ss amp can easily handle 120wpc into 8 ohms, but most of the time I'm only using less than 1 watt, will the "unused headroom" (if there is any?) of the power supply caps degrade? Suppose one day I get very hard to drive speakers and all of a sudden I'm pushing 15+ watts. Will the caps be "out of shape"?
