Default Re: AVO 163 amp board ~ transformers

Did some quick measurements with my caliper and it shows 0.15mm wire on the high ohm side and 0.3mm on the low ohm side, the thicker wire is wound closest to the center.

The bobbin is a double section type where it looks like the low ohms winding is only wound on the bottom section and the high ohms winding on both sections - it could be that the low ohms section stretches to the top but I can't see it there, except for one end exiting at the top.

The yellow and black sleeves are at the top side.
