Hi all experts,

I have a Schaller Rotor Sound that has some burned inductors and I am trying to identify and perhaps wound new ones. In total there are 18 dual inductors in this unit and it has a ferrite core that is 2 x 3H1 type.
From measuring a working one with a Peak Atlas LCR40 gives me a reading of approx 600uH/31 Ohm, 2.2mH/65Ohm per winding without the ferrite core. The schematic mentions that total resistance is 600Ohm/800Ohm.

It is a bit difficult to find out what wire they were using but it is approx 0.1mm(38AWG) in diameter and I get it to be about 500 and 300 turns respectively for wining 1 and 2. I tried to wind with some random wire that is 0.1mm as a quick test and it gave me approx 610uH and 16 Ohm, which is about half the resistance of the original coil. Is the resistance of high importance here, or inductance? Or both? I am a bit novice here so I would really appreciate some tips.
Thanks in advance and see attached schematic and picture of inductor. Also an image of a random unit from the web, not mine, just to see the complete unit.
