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?

I run a couple of hybrid amps and both have circuitry that allows the tubes  to be turned off when you switch to stand-by mode.  It means a delay when you fire it up again, but not as much as if you turned it off completely.  One is an Audio Research and the other is a CJ Premier.

Keeping your tubes fired up all the time will drastically shorten useful life.
