Figure 42-Inserting 1/8" jacks in the front panel
Install the headphone jack
Install the second 1/8” phono jack into the hole marked with the headphone pictogram,
fastening it per the detail in Figure 42. The headphone jack will have no wires at this
time. It is there to support an optional headphone amplifier (a future project).
Connect Power to the Tone Volume PCB
Identify the thicker gray cable and green ground wire coming from TB4 on the power
supply board.

Remove ¼” of insulation from the red wire.
Tightly twist the red wire strands, then tin them.
Remove ¼” of insulation from the black wire.
Tightly twist the black wire strands, then tin them.
Remove ¼” of insulation from the green wire.
Tightly twist the green wire strands, then tin them.
Insert the tinned green wire into the GND hole of the Tone Volume’s TB5.
Insert the wire into the solder side of the PCB, and solder it on the
component side.
Insert the tinned red wire into the POS12V hole of the Tone Volume’s
TB5. Insert the wire into the solder side of the PCB, and solder it on the
component side.
Insert the tinned black wire into the NEG12V hole of the Tone Volume’s
TB5. Insert the wire into the solder side of the PCB, and solder it on the
component side.
Double check the locations of the red and black wires to avoid a costly mistake.
Tone Volume Signal Wiring
In this section you’ll connect the already existing shielded signal cables from the input
selector board to the tone volume board. Insert the wires into the solder side of the board
and solder on the component side.
