Place the bobbin item [2] on the mandrel such that pin side on the left side. Winding
direction is the clockwise direction.
Start at pin 1, wind 64 turns of #35 AWG item [3] from left to right two layers. At the last
turn exit the same slot, leave enough length wire floating to wind next 64 turns in WD4.
Apply one layer of tape [6] for insulation.
Start at pin 6, wind 26 turns of #36 AWG [4] wire from left to right. Finish at pin 2.
Apple one layer of tape [6] for insulation.
Leave about 1” of wire item [5], use small tape to mark as FL2, enter into slot of
secondary side of bobbin, wind 22 turns in two layers. At the last turn exit the same slot,
leave about 1”, and mark as FL3.
Apple one layer of tape [6] for insulation.
Continue to wind with floating wire, 64 turns of #35 AWG from left to right two layers.
Leave 1” and mark as FL1
Apply three layers of tape [6] for insulation.
Cut FL1, FL2, FL3 wire length to 0.75”. Grind core. Assemble core and varnish using
item [7].
