Ed, All
I recently was given a box of electrical goodies (my friends say that if
it has a cord or used electricity, marc will want it) this box included
a working "westinghouse "rectigon" "cell charger" that uses a rectifier
that they call a "bulb" (looks like a light bulb). anyway, in the goodie
box is a " "zenith" vibrator part #190-22v.
Could this be one of what you're talking about? it is very heavy.

Take care,
Marc
