 >>> You can always make some shorted-secondary series inductors

 >>> I heard if one guy here recently that made a mini-pig from 8 
MOTs--don't know how safe this was.

 >>> I have cut out the secondary coil and wound a few turns of heavy guage 
wire and made a multiple-tap transformer--low voltage-      -PLENTY Amps!
