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,

Not in your bathroom.

Have a going away sale and presto no storage problems and a few more bucks in your pocket!

Funny how the power amps always sell first no?
since phase linear products have aged like fish, why wouldn't you just sell them?
