Primary pin side of the bobbin oriented to left hand side. Temporarily start
at pin 6. Wind 37 bifilar turns of item [3] from right to left. Wind with tight
tension across bobbin evenly. Cut at end. Finish start on pin 5.
1 Layer of tape [6] for insulation.
Start at Pin 3. Wind 72 turns of item [3] from left to right. Then wind
another 72 turns on the next layer from right to left. Terminate the finish
on pin 4. Wind with tight tension across bobbin evenly.
Use one layer of tape [6] for basic insulation.
Starting at Pin 6 temporarily, wind 10 quadfilar turns of item [4]. Wind
from right to left with tight tension across entire bobbin width. Finish on
pin 5. Cut at the start lead.
Use one layer of tape [6] for basic insulation.
Start at Pin 9, wind 13 turns of item [5] from right to left. Spread turns
evenly across bobbin. Finish on Pin 8.
Wrap windings with 3 layers of tape [6].
Assemble and secure core halves.
Dip varnish assembly with item [7].
