Emerson I assume your question regards solid state (vs. tubes which pretty much warm up almost immediately).
This really depends upon your particular equipment. Some would take 1-2 hours as others have experienced. My own: the PA takes a few hours. The PRE requires over a full day to sound its' best. Assume typically about 30 hours to attain full thermal stabilization with solid state.
When the line is bouncing I always unplug everything just as I do in stormy weather; those line transients are murder on your equipment.
