Princess phones used the yellow green pair for the dial light. A
transformer was hidden somewhere in teh house to supply the power
(IIRC, a standard 24VAC door bell transformer, but it's been a lot
of years).


The lamp was on yellow & black. Red & Green are the pair to the CO.

slap! There I was typing, looking at bud-'s post and *STILL* got
the wires crossed. I *shoulda* had a V8.

No big deal. Do you remember that wall wart being the first one
recalled for being a fire hazard?

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

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)?
