Tin each end with solder as before. Tin all the way up to the core body.
This winding is the primary of transformer T2.
44. Cut off another length of wire, 8 inches long. Wind 1 turn through the
core, loop out 1 inch, twist together and run one more turn through the
core, continuing on in the same direction as before. Tin each end with
solder all the way up to the core body. This winding is the 2 turn center-
tapped secondary of T2.
Primary leads
(wound previously)
1" long leads
45.Winding T1: Locate the remaining larger 2-hole ferrite core. Cut off a
10 inch length of enameled magnet wire and thread the wire
through the core 3 times, pulling each turn gently tight. That's 3 times
through each hole resulting in 3 complete turns through the core.
Again, the amount of wire cut for this task is the proper amount. If you
have too little or too much, then you have not wound the core correctly.
Tin each end with solder as before. Tin all the way up to the core body.
46. Cut off another length of wire, 9½ inches long. Wind 1 turn through the
core, loop out 1 inch, twist together and run one more turn through the
core. Continue on in the same direction as before. Tin each end with
solder all the way up to the core body. This winding is the 2 turn center-
tapped primary of T1.
