The dehydrator and incubator are doing the exact same thing. My only issue
with the Nesco options is that lack of a fail safe in the case of
thermostat malfunction. I addressed this by buying a temperature probe and
a REX C100 0-400 degree temperature controller and rigged it to kill the
power to the dehydrator in the case of over temperature. Cost me about 3
hours of bench time and a total of $40 in surplus parts. In the 5 years
since I put this together the dehydrators have never gone outside the
window and required to be shut off. (I set the threshold at 135F)
I have been baking all analog tapes that are known to exhibit SSS for a
minimum of 48 hours at 130F. The time required is often variable and some
problem tapes have required up to a week of time to become un-sticky.
THere is plenty of information about the problem and the solution out
there. One thing to remember is that plastic reels will begin to warp at
just over 140F.
All the best,
