I'm getting some huge ferrite cores in a couple weeks if anyone's
interested. Had to buy 1000$ worth before the company would deal with me and
thinking of putting the extras on ebay (only needed 16 U's for 2 giant EE
cores, 2 U's make a 4x4.5" core with a 1" cross section (about 1 kw power
handling at 200 khz).
