Copal R67, gears and possibly resistor

August 29, 2023, 06:37 AM

As per title, I have a Copal clock, 220v, that has the neon bulb still attached to the mechanism but no motor, gears or resistor. First photo is my mechanism, the second is from another page here that seems to show what I am missing. Does anyone either have any leads as to where I could hunt for these bits or whatever else I could use to replace them?

Well the resistor is the easy part .

I can't speak to the availability of replacement motor/gears. Others in this group could speak to that better than I can.

Depending on your abilities and determination, this approach may be a possibility.

I've been working on a microcontroller (Arduino)-driven stepper motor replacement for seized synchronous motors. My first effort was a GE 7-4305 clock radio. It worked great, but there's a lot of space inside that unit. Someone commented it would be hard to fit inside a smaller clock. Since then, I've worked on slimming down
