Found a bobbin coil calculator, that from the geometry and the resistance came up with the same number of turns (10% accuracy) that I calculated the coil had.
From it, the inductance is on the order of 7H.
So, unless I can find a bobbin one, I will have to resort to a Hammond cored inductance. And then add a resistor.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
