That was one of Western Electric's first uses of a third-party supplier.
In this case, it was Ault Manufacturing.

The Ault transformer recall was HUGE.

There are still MANY Western Electric dial-light transformers in service
to this day. Virtually all are powering NOTHING but have not been
unplugged.

We don't care, we don't have to."
