I wonder about using the plain old garden variety sheet metal (think AC duct
work) from the hardware store. Can anyone quantify just how bad this stuff
really would be for a core? I mean, if it's say 80% as good as real
transformer iron it would still be very acceptable for TC use. This would be
a real easy route to go-
