Hi Craig,
Yes, I did exactly as the schematic you posted, I do have two big air core inductors wired in series.
is it possible that the two inductors are cancelling each other if the winding directions are opposite ? (I id my best back then to match the winding directions to act as a bigger single inductor but I am not sure I have it right)
Maybe the moisture is shorting/making the inductors act as a simple conductor ? (35mm² "braided" copper with varnish insulation bought'em used)
After the test the bridge rectifier heat sink(no fan) was very warm to the touch and the inductors were warm to the touch, it was about 15°C ambient during the test.
Thanks very much !
