Hi Allison! Only the words are different. The time, temp, and results are the same. You are dehumidifying and heat treating the tapes whether you use a dehydrator or a convection oven. It is only the device in use for the same process that differs. One important detail is to not use a common household gas oven, as gas burning has H20 as a side effect. It needs to be dry in there, preferably with air circulation! A convection oven by definition uses hot air circulation, a dehydrator may need an accessory fan if the heat rising is not enough. That's why I like the Excalibur; they have a fan pushing air horizontally across the tapes, no hot spots. That said, I usually transfer the tapes I bake the following day, and haven't needed to go back and find out how long the effect holds. But six months or more later, re-baking is needed, according to my experience... <L> Lou Judson Intuitive Audio 415-883-2689 On Feb 24, 2014, at 7:31 AM, Smith, Allison wrote: > Hello and thanks to everyone who has responded so far to my post - > > I'm intrigued by the dehydrator solution. Richard, could you tell me what temperature you are setting the Nesco unit to, when you bake 24 - 48 hours? Is it the lowest setting? If so, I'm wondering if the dehumidification process is less stressful / radical than traditional convection oven heating (higher temp for a shorter period of time) - letting the tape layers relax into place more naturally/gently? Or, does this matter? Anyone done a study? > > For those of you using the dehydrating solution - do you have a temperature/time ratio that you generally use, that you would share?
