Do you leave the Jeff Rowland Amp on all the time

Turn it off. NO excuses. It's lame to leave things on all the time, wake up, get in the 21st century you wasteful laggards! Use the time it takes for your gear to warm up for something useful...charity work, gardening, flossing, put the LPs back in alphabetical order, explaining to your partner that Donald Fagan really does have a good voice, clean your motorcycle, check your butt for deer ticks...

I agree with Wolf. Turn it on and do something for awhile. Were using more power than ever. For every energy efficient invention there's a new invention that plugs in. Turn it on and set a kitchen timer for 20 minutes.

I keep my Sunfire SRA on all the time, but it only uses 10W of idle power. It's even longer for digital amp to worm up to normal operation.

100 Watts when idling? I don't think so. Maybe 1 Watt. Hel-looo!

NO WAY!!!!!!!!!!!
Donnot leave them on 24/7
That is just the company trying to get you to wear it out for repairs or a new one down the road.I talked to 5 well regaurded techs and they all say the same thing""SHUT EM DOWN"" but thats just my experience.
