This reminds me of the "grandfather clock" thingamajig I saw at the British library. It is a large board with rollers that the tape goes through making a serpentine. The tape travels very slowly and can be heated or chilled as needed. They made this for some agfa tapes that stuck. I have never had a 3m 176 make trouble but this sounds like many 50's 60's tapes I transfered that were of American origin. One squealed so bad we had to soak it with silicone. I am wondering it there is a benefit to slow winding under a cold air blast, like an air conditioning duct pointing at the transport. My a/c/ has a setting for drying the air. Very cold air forced out and the rh drops very fast.. Shai Richard L.
