I acquired a Eureka clock which I plan to service as soon as the new wears off. It is a "four glass" model.
It is running fast and on 3 volts. I haven't tried it on a lower voltage but will soon. I'm aware they were made to run on 1.5 volts from an old #6 dry cell (no longer made).
Does any of the group happen to have a simple circuit for a governor or an efficient voltage regulator?
I believe at one time someone made a device which pulsed the supply voltage at either 1.3333 or 2.6666 seconds which would tend to synchronize the clock.
It may be that a good cleaning of the balance bearings and the clock would run on 1.5 volts and keep some kind of decent time.
I hear mixed reports on how well these clocke actually kept time but now I want to find out for my self.
The contact flag and pin look to be perfect.
