I have a Butler TDB2250 power amp. When I sent it in for some repairs I talked to B.K. Butler the owner and designer. He told me that leaving the power on was just fine. My amp doesn't have a standby mode. If it did I would use it.
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?
