Pull pins 7 and 10. Orient the bobbin with primary pins on the left hand side. Winding
direction is clockwise.
Start on pin 5 and wind 19 turns of bifilar item [3] from left to right terminating on pin 3.
Apply 4 layers of tape item [6].
Start on pin 2 and wind 39 turns of item [3], with tight tension, from left to right filling one
layer. Apply one layer of tape item [6]. Continue winding 38 turns of item [3] from right to
left and apply one layer of tape item [6]. Wind the remaining 38 turns of item [3] from left
to right and terminate the winding on pin 1.
Apply one layer of tape item [6].
Start on any temporary secondary pin, leaving extra wire, and wind 16 turns of trifilar
item [4] from right to left filling one layer. Secure the winding temporarily with tape and
cut the finish end of the winding. Move the starting end of the winding to pin 1.
Wrap two complete layers of tape over any leads of the previous winding.
Start on pin 9 and wind 7 turns of item [6] from right to left terminating on pin 6.
Apply 2 layers of tape item [6]
Assemble core halves and tape together after properly gapping center leg of core.
