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.

That is very easy to explain: "Rowan & Martin's Laugh-in" with Lilly
Tomlin as Ernestine, the telephone operator: "We're the phone company.
We don't care, we don't have to."

How about driving a generator in the basement with either a heavy

axle rod driven at some distance by a (sacrificial) motor, or by a fluid
that
does not conduct electricity through a turbine system, similarly driven by
a
motor/pump at some distance.

Or a compelete diesel-hydraulic locomotive? (Diesel-hydraulic coupling,
Dieselhydraulische in german)?
