I think I've got it, check this drawing, please.
Another thing I don't understand is what is happening with my self wound inductor.
I started with 46" of ~20 ga wire and measured it's inductance, 1.41 uh, put one pass through the core, measured it, 3.01 uh, another pass,7.77, another pass,15.2, then 25.7, then 39.19 and one more gave me 55.6uh.
When I tried to plug it into a circuit that was working with a 34uh inductor, is wouldn't work anymore. I had tried it with some commercial inductors of 22 uh, 33uh, 44uh and even the 22 and 33 in series and the all worked, but not my self wound, even though it measured similar values.
Did saturate the core? did I use the wrong wire, poorly wound, any ideas? See photo, please.
Thanks for help,
