Wow! All this valuable info.

I have five 7inch reels.
Someone has probably told me this already, but what setting [if there is one] on the dehydrator and for how long?
I'm going to Walmart or Brandsmart later.

Thank you all so much.
Ben

You can buy direct from the links I previously posted.

Many of us receiving tapes that had been stored "in the wild" vs. "in captivity" see baking times of 24 hours as common. It surprised the good folks at the archive when it came up in our discussion.

This creates problems for reels that have acetate tapes inside a layer of need-to-be-baked tape and there is no good solution for it. Fortunately, you may be lucky unwinding the tape that needs baking as the acetate tape is closer to the centre of the reel and the outer wraps did not have the higher pressures that the inner wraps would.
