Warm Up Time Tube Phono Preamplifiers


New to tubes, wondering about warm up time for new Project Phono DS Box and after listening is it wise to turn off? I leave all solid state gear, amplifiers, sources on or at least in standby.

You should turn off your tube gear.  Just wears out the tubes.   Usually tube gear sounds best after 15-30 minutes.
I am good to go on my phono stage (Rhea) about half way through the 2nd side of my first LP.
