___
Using the winding chart on page 5, cut a 38 inch length of wire for L8. Hold about one inch in one
hand with the toroid and wind the wire around the toroid as shown in figure 1 for 33 turns. You
should space the wires evenly around the toroid as you wind them. Once you have completed
winding L8, trim both ends to one half inch and scrape away the insulation from them. Do not
install L8 until later.
___
In a similar manner, wind L7 through L5, using the winding chart for lengths and turns. Trim and
scrape thermaleze coating from #18 wire. The thermaleze wire cannot be soldered unless the
thermaleze coating is scraped off.
___
Wind L1 through L4 as shown in figure 1. Place all windings of the bottom of the toroid.
___
Wind T1 with 10 turns using the red and green #28 gauge wire. T1 is the small, black toroid just
under one half inch in diameter. See figure 2 and wind this in bifiliar fashion by using two lengths
of wire and winding them at the same time. It doesn't matter if you twist them or wind them side by
side. Note: you must wind this in the direction shown in figure 3.
