I am also using a Fisher Scientific incubator oven. The tape has been baked three times in the past 2 weeks at 133 F for 9 hrs each time with no noticeable improvement. I am considering let it sit for a month or so, and rebaking it for a longer period of time as suggested. If that doesn't work I will try to use isopropyl alchohol which admittedly makes me a little nervous... Ive baked probably close to 30-40 reels of 226 and they have all played back fine after the first 9 hr bake. I wonder why the 227 is being so stubborn. Thanks for your help! mike ---------------------------------- Michael Bridavsky Audio Engineer Digital Audio Archiving Project Indiana University School of Music Office: 812-855-6061 Cell: 812-327-7939 -----Original Message----- From: Association for Recorded Sound Discussion List [mailto:[log in to unmask]] On Behalf Of Robert Hodge Sent: Thursday, March 30, 2006 12:08 PM To: [log in to unmask] Subject: Re: [ARSCLIST] scotch 227 Hi , I thought I'd my experience with a reel of tape that also wouldn't respond to baking.I've baked dozens of reels successfully , with the exception of this one. Extending the baking time and raising the temperature made not one bit of difference in the playback results . My results were exactly the same as yours. We use a Fischer Scientific oven with very accurate temperature control. There is no question about it being SSS. The recording it contained would fit in the period of the early to mid 70's. I could never identify the manufacturer of my tape as it was on a generic reel metal reel that would have once held acetate tape.. It is .50 mil. tape. I offer this information for what it's worth.

Most of our recordings made in the mid-late 80's and easrly 90's was recorded to Scotch 226. It's all pretty sticky, but bakes well. I have just encountered a single reel of Scotch 227. It seems to be a thinner tape than the 226, ad Im assuming it was an economy version of 226. It is also sticky, however it does not respond to baking. While the amount of deposit left on the heads and guides is minimal, and the tape passes through the transport without slowing, the squeal and distortion is audible in the transfer. Does anyone have any experience with this tape? Any suggestions or other treatments that might get it to run smoothly?
