Magnet Amplifier (new info)

@SoundHappy - Not quite sure how to test these.
The part number is Western Electric GA-10654 Magnetic Amplifier.

An externally hosted image should be here but it was not working when we last tested it.


All that i can find is this:

They are quite large 7" x 2.5" x 3"

If you are interested, i can send you one to experiment on, for a long term loan?

At the moment i feel like a child who doesn't know how to eat ice cream
 
Any progress in this interesting field? I'm eager to know if anyone has put together something worthwhile to build, following a schematic. Many links to images here are broken or don't work. How is it possible that there isn't already a well-established and tested circuit for this in this forum? I hope we'll soon gain practical knowledge of these very particular or unknown types.
