9.
Cut the red and orange transformer wires to a length of about 2”.
10.
Remove 3/8” of insulation from the red and orange transformer wires.
11.
Twist the insulated parts of the orange and red wires together. Now twist the bare
ends together and solder them to each other. Slide a 2” piece of 1/8” diameter
(black)

heat shrink tubing over the pair of wires, about half on, and half off.
12.
Use the tip or the barrel of the soldering iron to shrink the heat-shrink tubing all
along its length.
13.
Once the heat-shrink tubing has cooled, test your work by tugging on the heat
shrink to assure that it will remain in place.
14.
Cut the black and yellow transformer wires to a length of 3.5”. Twist together the
insulated portion of the black and yellow transformer wires. Twisting the pair
reduces hum.
15.
Strip 3/8” of insulation from the black and yellow wires of the transformer. Twist
and tin each wire, preparing them for installation into the power supply in a later
step.
Transformer Installation
1.
Set the transformer into the chassis, wire side up, over the raised circle in the
chassis floor. You won’t bolt it into the chassis until after the shield has been
installed.
2.
Twist the transformer primary leads (that’s the transformer wires with the
FASTON connectors) together to form a twisted pair. Slide the FASTON
connectors from the toroidal power transformer thru the switch cut-out in the front
panel. Connect them to the indicated switch terminals. Place black over black and
white over white.

3.
Insert the switch in from the front of the chassis. It may be a snug fit.
Make sure
that the | is at the top of the opening
before you insert the rocker switch into the
chassis. Push the rocker switch in the rectangular opening; it will click into place.

The transformer in some kits has thicker insulation for the orange and red wires. In that case, the black
1/8” heat-shrink won’t easily fit over the wires. Instead, use a 2” piece of the white 3/16” heat-shrink.
