    ASAP: how effective is this for prevention of eddy currents

    It seems quite effective since the majority of the transformer is insulated which prevents eddy current formation due to the lack of a conductive surface. However, I would add that it may not be the best setup since it inhibits the ability to form flux linkage due to a lack of iron bars in parts...
