At work I turn most things on at the start of the day and off at the end. I have a
reasonable idea of what is needed for the day so I dont need to switch everything on.
Switching on is the most stressful time for electrical equipment - light bulbs usually
blow when they are switched on- but they are designed to deal with this, or should be.
Obviously valves have a finite life and capacitors do too albeit a lot longer. Think if
you need all your valve equipment running 24/7 just to keep it warm?? Depending on how the
mains is handled in your studio it can be an idea to unplug things during a major
electrical storm, perhaps an extreme example....or you could be outside recording thunder
and lightening with your handheld recorder or running to the pub "for safety".
