Old Doble Transformer Demagnetizer circuit

[Millbo]

Would any of you gentlemen have, can post or know where to locate the circuit diagram for that transformer demagnetizing setup I beleive Doble put out a while back.

If memory serves, it had a manual transfer type switch (400A?), a resistor, a shunt and an analog DC meter. It also used two car batteries for the current source.

Switching arc was contained within the enclosure.

Any help would be greatly appreciated.

Thanks,

Mike
