Good tip Slider2732!

So I put the chip into my build. Still without any inductor, I'm playing around. Some interesting behaviour again:

An inductive 0.33Ω resistor?

An inductive 0.33Ω resistor?

Well, the 0.33 ohm is made up of the three 1 ohm metal-film resistors in parallel. So there is some small inductance there. But would it make any difference, where it is in the circuit?

If I'm reading the schematic right the main inductor has 27 and 54 milliHenry windings, not a tiny value at all. In fact I don't see how the heavy windings on Akula's flyback core ferrite can reach those values. I've already put a few hundred turns on mine and am only up to 6 mH or so.

I did hear Wesley say 5.4mH in his translation video.
