Hello Matt,
I'd be more concerned about NOT baking the backcoated reels, or you'll find the same fate that my Heart master dub had. If you don't believe me, try it on a loser reel for yourself. Besides ruining the recorded media on the reel, you can also look forward to anywhere from 5 to 30 minutes cleaning your machine.
To properly bake a reel, you need to slowly bring the tape temperature up to 140 degrees in over an hours worth of time, let the reel stay at 140 degrees for about 10 to 15 minutes, then slowly reduce the temperature of the reel over an hours time. The professional ovens designed specifically for this cost around $400 used, which is what I'd paid. They are very hard to find. I have friends that have used a fruit dryer with a decent baking thermometer, a timer and a small Variac that have gotten great results on a budget. Do you have some patience to experiment? If so, try it out. If not, go back to easier format, as reel is anything but easy and convenient.
If you need any further advice as to starting temperatures/temperature intervals, feel free to e-mail me directly. Be aware that my business has me away from my home for the next several weeks, so please be patient with me. I'm ususally around on the weekends.
Kind regards,
Brian Weitzel
