Occasionally we run across tapes with Sticky Tape Syndrome, primarily Grand Master 456, that does not respond to tape baking. When that occurs, we dig into an out bag of tricks and resort to some tried and test methods of getting the tapes to play. This tape was baked for 24 hours, and after colling down to room temperature, it still would not play properly. With the aid of Cyclomethicone (D5), we were able to get these tapes recorded from the late 80s to playback properly.
