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. This winding is the primary of transformer T2.

ˆ44. 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.

ˆ45. 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 whole 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.

ˆ46. 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.
