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

I turn mine off when not in use. Have you seen the price of NOS 6H30's? At $200/pop, it'll cost you $800 to re-tube your VK-31SE with them.

for tube pre-amp-- its ok to turn off when not in use.
for solid state pre-amp-- its better to leave on all the time. These takes time to warm up.

Since I get to listen mostly over the weekend, I turn on my pre on Friday evening and off Sunday evening. Minimizes tube loss.

I was blissfully unaware of the cost of the tubes. It will cost me roughly $500-1,000/year (Canadian) to keep my pre running?

Bsmith15, when I was hot and heavy into listening to my system, especially during colder parts of the year relative to LA, I'd do exactly what you do.
