How do I correctly store 10 new preamps?


I came accross a handful of brand new 25 year old Phase linear preamps.
I sold a few and now I have to focus on work so I have to store them for a year. Is the attic ok? The cellar? Keep in mind that i have a 5 foot stack of them new in boxes so its not like I can just stick them in a corner of the living room.
Thanks,

Keep them someplace that's environmentally controlled. Avoid temperature extremes and especially humidity.
Good electronic gear stored in: damp cellar, extremely hot and humid attic, or climate controlled home? Hmmmmm! :-)
Start with the attic and a temp/humidity gauge.Better to have it a little hot than a little damp.If you live in Az,forget this advice,good luck,Bob
