Re: [TCML] MOTkenstein

If I understand your suggestion, you're effectively doubling the height of the windows in the core, however the cross-sectional area of the center leg remains unchanged.  So while you've got twice the steel, you haven't actually increased the power capacity of the core at all; it would still only handle the power of a single MOT.
