This device comes from free pile (count me in when it's free) of old broadcast gear at Early Television Foundation conv.
It appears to be late 1950s as it has socketed Germanium transistors and heat-sunk Delco 2N555 power transistors plus this mysterious large component assembly?

Unknown object

Can't wait to see the pic. Can you email it to me? Sounds like a power supply...

A valve a day keeps the transistor away...

That is a magslip - used for some control purpose.

The gold pancake is a synchronous motor with reduction gearing to shaft (at first I thought it was a rotary-solenoid.)

This free gear I took from heap was mainly old (B&W) TV camera-control-units ('CCU') - There were also come old rack-mount sync-pulse-generators ('SPG') (but these do not use anything electro-mechanical)(...or do they?...)

Is that like a "selsyn" system for positioning antenna direction by remote control?
Fred.
