QAMP-30 • 11
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.
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.
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 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.
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.
