The fact that Ten-Tec used aluminum when steel would have been cheaper is
interesting, especially since steel is much better at attenuating magnetic
fields. Perhaps they just had a bunch of aluminum around, so they used it.
It is much easier to cut and bend than steel.
Again, I don't think aluminum will do anything, as it is non-magnetic;
cardboard would work as well.
Anyone have the definitive answer on this aluminum issue -- and what TT
was hoping to accomplish with the aluminum around the xfmr?
