FWIW, that's what I do, unless I'm out of town or know I won't be using the system for a while. And my equipment, Jadis, is much more "on the edge" than ARC, in terms of whether anything can go wrong. I am trying to convince myself that the turn on/turn off cycling of the tubes wears them out faster than leaving them on all the time, but I think that argument is the same as leaving your car running all the time instead of turning it off and starting it up when you use it because you use more gas starting the car than when it's idling! Nothing has gone wrong yet, but my fear with this practice is that something might go wrong enough to cause an electrical fire while I'm not there; don't know if that's reasonable or not. Any more informed opinions?
