Leave it on?


I just listened to Paul McGowan explain that turning SS equipment on and off degrades the capacitors from the tiny power surge and that leaving SS equipment on ALL THE TIME is best. What do you do?

Hi.some of my equipment have manufacture shut off automatic.xconsult the manual and have fun

"Do you hear any appreciable difference with your thermal magnetic switches in?"

The only physical changes were adding a thermal magnetic switch in the wall to the hot wire feeding each amp, and then removing the (pretty good - recent SR color) fuse installed by SMc Audio and replacing it with a1/4-inch, 99.9 percent copper rod that was burnished smooth.

To your question, no, I do not hear any appreciable differences that I would reliably attribute to changing out the fuse for a thermal magnetic switch.  I am not surprised.  However, I do get to turn my amps off without unplugging them or turning off the breaker at the main electrical panel so I am happy with the win. 

@mitch2 ,

I score it a win if it didn't degrade the sound, plus it was a cool things to do!

You know this, some things can be left on all the time, and some things can't. I wouldn't leave any tube gear on all the time unattended, on the other I think solid state could benefit from being powered up for long lengths of time. It could be true that the act of turning SS on and off a lot with the in-rush of current could increase the risk of component failure.
