24/7 operation definitely shortens tubes' life in ALL cases.
Moreover your electricity bill grows.
Unswitching tube components after the tubes rich the steady state(10...15min for preamps and other small signal tube components) will NOT shorten the tubes' life.
Switching back tube components after they've riched an initial state(5...7min for preamps and other small signal tube components) will NOT shorten the tubes' life.
Under the initial state we should define the state when no emission of electrons takes place from cathode i.e. the tube is literally cold including the tube base if such exists.
The positive issue living 24/7 tube component operation is that your system is always ready to play. Some components improve the sound during staying unoperated for another hour after the steady state but only on couple of small quantums of relative improvement(Someone recently posted a thread about quantum-tweaking units:^)-).
The power tube amps can be maintained the same way with 1.5x...2x longer intervals(think logically!).
These thoughts shared with me by VTL customer service and they realy work.
IMHO it doesn't make a sence to live components overnight without work.
I often call the babysitter to turn my tube-rig on(just only one button) when I finish working so I can come and listen.
