8.1.3 Hookup the Leads to the Baby Will
The board is installed in the chassis, but we still need to hook the high voltage
supply, heater element supply, and output transformer.
Guide the high voltage secondary leads to the T1 and T2 locations on the board.
Add some extra length (½” or 12mm) and cut the wires. Strip ¼” of the insulation
from the wire, twist the wire ends, and tin the end of the wire with some solder.
Insert one of the leads into T1. Insert the other into T2. Make sure the leads DO
NOT extend to far through the board and touch the metal chassis underneath.
Solder the leads into place from the top of the board.
Repeat the process described above for the heater and output transformer leads.
Here’s an image of all of the hookups installed and soldered into place.
Fasten the ground wires from the Baby Will circuit board and the output
transformer to the star ground screw post.
