Gotta agree with Dee. I knew there was copper in there, but it would not bust open with a 3 pounder. So, bigger hammer. After a few whacks with the 10
pounder I finally got to see the copper coil, partially, still embedded in some resin. Never did get it out. Not worth the the effort. Now they all go in with the
motors/xformers as soon as they are off the board.
