Re: [TCML] Disassebling a huge transformer

[Chip Atkinson <chip@xxxxxxxxxx>]

As I understand it you want inductance and not DC resistance, right?
Of course if the ribbon part was the secondary, you'd have to deal with
large amounts of current at low(er) voltage which would probably be more
difficult than, say, 120v at a lower current.
