Please tell me whether this is an inverter or a bridge rectifier, if you
recognize it out of circuit context.

Selenium stack bridge, by the looks of it. Equipment it's in ?

Ancient European slide projector with rotary carousel. Trying to help a
friend get the thing going again, via email since he lives in another
city.

Problem with it is that this motor:

turns very slowly.

It didn't make sense to me that a rectifier would be fed by a motor
winding, but there you go. So now it seems the motor is 240, but there's
a secondary winding in there putting out about 17, and he's getting
about 12 VDC out of the bridge, so that part seems OK now.

Is there anything on that type (shaded pole?) of motor to fix, or is it
an R & R job? (remove and replace)
