My "cooker" is home-built and heavily insulated.  It has a 75W
incandescent for heat and a low-speed fan for circulation.  I use a PID
controller to keep the temperature within limits. An RTD sensor sits in
the middle of the chamber.

With spacing for air circulation, I can do about 7 tapes at a time.  My
"tape tower" is constructed from a trimmed-down PVC toilet flange
attached to a 3" lchedule 80 PVC pipe.  Spacers are made from 4"
diameter schedule 80 PVC, which fits nicely into the write-enable ring
recess on each reel.

Because of the insulation, it uses very little electricity.  There's a
70C thermal fuse just in case things get out of hand.
