so are you shutting off both units??
or just the 11r??

you are in the Midwest too...
I always shut down everything I do say everything after use.
lightning is a big thing this time of the year.

do you use apc ups units on your gear??
that helps!!

also on the heat, rack it with good silent fans is a good idea.
burn 2 rack spaces one above and one below to help.
be sure to use filters on the fan intakes and run positive fan pressure on the rack, that way dust on the pcbs does not get to be an issue!!

or best yet do it like the computer labs and run the temps at 64 deg year round... nice and dry and cool!!

and separate from the guitar booth as the guitar needs the solid humidity and temp.
