Quoted from Mopar:This.
I'm in Upstate N.Y.
I'm not sure how many, but well over 100 I've had 60s and 70s machines stored for many years (some 20 yrs. plus)
in more less a garage type atmosphere, and recently start setting some up, and no problems what so ever.
However, like already mentioned, if any of their backglasses are sealed (sprayed), you most certainly will want to keep
them out of the cold.
Yeah, so many old timer EM collectors years ago had 50+ pins stacked 3 or 4 high in garages for years on end. Backglasses *could* be a concern, but I don't think the mechanics are. I have a bunch of EMs out in the cold part of my basement as well right now, but wrapped in blankets and plastic wrap. Should be fine.
