The everyday use of a tube amp


Hello everybody,
I know this seems to be a stupid question but hey! still have to learn... I am working at home, listening to music all day long. Until now, things were like that :
Day use, SS integrated, tunrned on the morning with the radio or music server, turned off in the evening. Muted when I need to stop the music or during the meals.
In the evening, tube amp and Turntable for 2-3 hours, serious listening or during Fly tying sessions up to late night.
I will build a new system, all tube (Dodd pre and 50Wmonoblocks), so my question is:
Excepted for the tubes that I will have to change often, is there limitations leaving the system turned on 18 hours a day? I think that it is better to leave it and to mute when I need, even for an hour or so, than to turn it on-off and so several times during the day. Thank you for the help!

If you don't mind the tube bill, all the tube equipment I have bought says it sounds better after 15 - 45 minutes warmup. I have not done any rigorous testing on this, but it seems to be true. The only other issue I can think of is heat. Some tube amps put out a tremendous amount of heat, which builds up in a room over the course fo many hours of on-time.
I would not wait for a tube to completely stop functioning before replacing it. Tubes can get dull sounding and still function. I have had this experience. Some tubes in a particular design may be more critical than others. The manufacturer may be able to tell you which. This happens with video CRT tubes also. Users wil be happy with a CRT for years, until one gets replaced and it is much brighter than all the others. They lose brightness over the years, but so slowly, you don't realize it. The net result si that when you own tubes, you end up constantly wondering if your system is going dull, and when it's time to re-tube.
