Some of the Simplex Millenium lens turret power transformers are failing. What the symptom is: dead turret motor. Problem traced to the power transformer being "open".
DON'T THROW IT AWAY! You can fix it!
Unwrap it a little bit and you'll find the real culprit: a thermal fuse that's opened up. Just cut it out and splice the wires together to bypass it. Saves waiting for a new one.

We've had those turrets die and then come back to life for no apparent reason... do you have an idea how that might have happened?

The thermal fuse inside the transformer has been the main problem followed by PC board failures. Also be aware that some turret motors are AC and some are DC. Each type has a SIMILAR looking PC board. You must use the proper board with the proper motor type, i.e. DC control board with DC turret motor, etc. so be careful.
