So, I sat down, and first tried 40 AWG wire. It broke quickly. I retook diameter: this one was 0.05mm whereas the one I took off was 0.08 to 0.09mm.
I took AWG 38 I have, which is 0.09 to 0.1mm, and in 30 minutes or so put manually 580 turns (it was 700). Condisdering this is a filter choke, this should be just fine.

I took the ohhmeter to it, and it gave me 64-65 Ohm (66 is the target), so that was right on, and the inductance on my LCR was 5.2mH (my first calculated value on one of the inductance calculator was 6mH).

So it is just fine.
I took a candle and heatgun and potted the open wire.

Tomorrow I will connect it back and try to power up.
