Friends:

I can not speak to the subject of tube amplifiers specifically, but in my 
experience, I have found that a PA system draws almost as much idling as it 
does during a performance.  I suggest that if you need to conserve battery 
power, after sound check that the amps be shut down.  Sound crew hates 
this, they want to have the system blasting to prevent anyone from enjoying 
a decent conversation, but it is one way to prevent a shut down during the 
encore.
