Tube pre-amps: turn off when not in use?


I just recently purchased a BAT vk-31se - my first true tube product (aside from MF tube buffer). I normally keep all components on, day and night. Was just wondering if any of the more experienced tube users turn off their components when not in use to increase tube life.

Thanks,
Adam

here's a discussion of the "standby" mode on a BAT VK-30se preamp with input from Victor Khomenko of BAT. I'm pretty sure the VK-31se behaves the same way.

I suppose, depending on the manufacuter, the standby mode may work differently to keep the amp/pre amp toasty?
interesting question==i have both a tubed pre-amp and amp==i usually turn on my equipment about an hour before i sit down to listen== thanks doublel@mwt.net
