I disassembled the shorted transformer I am looking for here https://www.badcaps.net/forum/showthread.php?t=9302
As I discovered, it is transformer with 2 primary wirings and 1 secondary wiring.

The black number shows number of loops and the red which layer it is. One wiring is splited in two parts (57+51 loops) where first part is first layer and second part is the last layer; everything else is between these two parts. I guess it is for better wattage throughput but I think the whole wiring could be as one layer. This is thing I'd like to have confirmed from you
Anyway, it looks like the transformation ratio is 18:1 and 6:1. Do you have an idea where to buy such a transformer?
I tried to re-wind it, but no success. When I solder only the primary, there is voltage changing, but after soldering the secondary, too, there is only up to 70 mV. It probably could not push enough power through...
