I leave my Dehumidifier on all the time..Set it at one setting and run a drain line outside,so you don't have to be home to dump water..That should be you first and most important line of defense.....Keeping the dust level down by covering them with towels is also a good idea.....
tubes and moisture
I run almost all tube based gear. I live in a very moist,damp basement apartment on coastal northern California. I already use a dehumidifier every other day and cover my gear with towels after every listening session overnight and during the day while at work. Is this enough protection and what is the worst scenario here in terms of gear damage?
