Now it's time to use the #4 hardware and "L" brackets to attach the
front panel to the circuit board. Before beginning, take a good look
at the "L" Brackets and note that one of the holes is threaded and
the other is not.
( ) Attach the "L" brackets to the circuit board using two
4-40 X 1/4" Machine Screws through the board from the
solder side and then through the unthreaded holes in
the "L" brackets. Secure each with a #4 nut. Some
adjustment will be required when the board is attached,
so do not fully tighten the screws.
( ) Bend the LED over so that it engages the hole provided
for it in the front panel as shown in fig 2. Attach the circuit
board to the front panelby passing 4-40 X 1/4" Machine
Screws through the panel from the front and into the
threaded hole in the "L" brackets. When satisfied with
the alignment of panel, LED and circuit board, fully
tighten the hardware.
Finish panel assembly by connecting the remaining wires from
the circuit board to the jacks and controls on the front panel.
Solder as indicated. Proceed with wiring by columns, doing
all the wiring in fig 4 before continuing with wiring from fig 5.
This order will prevent installed wiring from blocking access
to future connections.

Note:
Be careful when
soldering the wires to the
switch. Too much heat
can soften the body of
the part causing the
solder lugs to shift
position. If you are using
a 30W or less soldering
iron there is little danger,
but higher power irons
should not be left on the
lugs too long.
