For the general rule of thumb and for the safety,
First load the tube amp or any amp(plug in interconnects and hook up speakers or dummy loads) than worm it up loaded.
If you turn it off after you worm it up the rail caps will likely drain the charge faster than they would accumulate. In my tube amps it takes nearly 20 min to charge completely. The plate voltage riches 510V almost instantly but to rich normal 530V takes another 20 min AFTER you turn it off and turn back on.
If you leave home turn your tube amp off or if you want to leave it on than connect it to dummy load since if there bad tube suddenly appeared it can do very bad things to the rest of amp and speakers if you don't act ontime.
Compared to SS poweramps that may require substantially longer worm-up time you can enjoy the music of tube amp after 25min and after another 20min you will experience some improovement due to the signal path worm-up as well.
Turning on/of tube amp freequently can shorten tube life but if you leave it for long time without listening you will short tubes' listening life.
The best way to A/B speakers is to have preamp with balance control and mono mode by connecting different speakers to different poweramp channels and muting either one speaker or the other. Otherwise you should turn off, hook-up and than turn on again and play only after 25min.
