I just leave my tube preamp and tube DAC on all the time, unless I'm away for more than a day or during thunderstorms. I have no problem with tube life.
Tube Preamps Should Have This Feature
So it's late or you just want some casual listening for a short time. "Should I fire up my tube pre for 30 minutes?". My answer is "No". Why not let me flip a switch (or push in the volume control) to put my pre into "bypass" mode? Bypass would, effectively, convert your pre into a passive device, keeping the tubes dark.
This sounds useful to me.

@ghdprentice both my pieces of equipment have tube rectified power supplies, no solid state devices in the power supplies. |
@ghdprentice power tubes do age faster, but those are in the output stage of an amplifier, not in the power supply section usually, though some power tubes can be used as rectifiers and in some regulation positions. |
@ghdprentice my preamp is space tech Lab qa112 and my DAC is also space tech Lab DA24/196, I'm using a separate power supply with the preamp called a super rectifier STR104 with two 3b22 rectifier tubes each rectifier tube has a 6amp heater current. |
