Is it a OK to leave tube pre-amps powede up 24/7

I’m relatively new to tubes in my hifi setup. Recently went from SS pre to tube ARC pre-amp and a Croft phono stage.

I have always kept all of my SS gear powered up 24/7(and still do), but I shut down my pre-amp and phono stage now after I am done listening for the day. I power them up at least a half of an hour before I put anything into play.

I would prefer to leave my tube gear on all the time, but am concerned about premature tube wear.

What would the tube folk here think about 24/7?

My tube preamp designer said to keep it on all the time for best sound and tube life. He said turning it on and off is more stressful for the tubes in his design.

Amen! My thoughts and experiences also Atma.

Well Atma is spot on as usual.  It depends on design. The tube preamp I have owned for years, TRL, ran barely warm and was a better climate for the parts inside.  The designer always told me to keep it on unless traveling for days etc...

This actually led to better sound, happy internal parts, and longer tube life according to the designer.  

I have never heard of a tube preamp catching fire and Atma's comments cannot be improved on.
