Hi, Steve, My recollection back in the day (70s, 80s?) when Capitol bought out Audio Devices/Audiotape was that there were new formulations with the Q number. I have seen some of this back-coated tape go sticky shed like many of the other brands. I am not aware of a listing for Audiotape/Capitol (nor Ampex/Quantegy) like we have for 3M and IG Farben/Agfa/BASF at the AES HC website.
