Should I leave my SF Line 3 SE on standby?

Semi,

If you only listen to the Line 3 SE on the weekends, I agree with Rec's statement. Even on "standby", the tube life is being used up, although only at 10% of that when they are "on". That "10%" is from an old brochure that SF put out a while ago (I have the Line 2SE).

Regards,

David

I keep it ON or on STANDBY all week and turn the whole thing off on weekends.

I have a very similar situation, I leave my system off all week and turn it on Friday and leave it on until Sunday night.
