The kit has three inductors that require the user to wind it first:
The inductor L8 is wound with a yellow enamel wire 10 turns, and the inductor L9 is wound with a red enamel 12
turns, see photo.
The T3 transformer is an 8:2 transformer with a primary red envelope wrapped around 8 turns, a secondary with a
yellow enameled wire wound around 2 turns, and a primary (red wire) welded to the two pads near the front panel
(near C39), secondary (Yellow) soldered to the two pads near the back panel (near 78L05).
L8, L9 and T3 should be soldered with a soldering iron before the PCB is mounted on the PCB and soldered to
ensure reliable soldering.
Install the middle of the mark "5" at the positions of L3 and L4, and the middle of the mark "2" at the positions of
L5 and L6.
