Install trifilar transformer
The trifilar transformer is installed in the position coloured red in this diagram. The photo (right)
shows the board after installing the trifilar transformer. But it is a tricky part of the assembly, so
please read and follow these steps carefully.
Firstly, the wire. The best way to un-wind it, without tangling it
up, is to think of what the kit-packing person that wound it up
did. Then reverse his steps. So, first unwind the tightly wrapped
part in the middle where the end of the wire has been secured.
Then, open out the spool of wire so that it is a circle. Then
unwind the spool, around your fingers, reversing the process of
winding it in the first place.
