16) Assemble T7.
Broadband transformer, 5 bifilar turns 0.31 enameled wire on the binocular core made up
of 2 small sleeves. Cut a pair of 12 cm long enameled wires, and thread through the core.
1 - 2 is wire A; 3 - 4 is wire B. Connect 2 (the finish of wire A) with 3 (the start of wire B) as
the tap (Use Ohm meter to identify each wire). You don’t have to twist the wire. Leave
about 1 cm for each lead. Remove about 5 mm enamel from the leads, and tin. The tap
goes to the center hole. Note: 0.31 wire is different from 0.42 wire. The enamel is not a
solder aid with 0.31 wire, you have to scrape the wire ends and tin them with solder.
