Section 3: Tone Control Switch

Before You Begin

It's important to check C16 for leakage. The quickest and easiest way to do so is to rotate

the bass control while the PAT-4 is connected to your power amp and speakers. Listen

carefully for a scratching sound as you rotate the Bass pot.

If you hear the scratching sound on either channel, then clean the bass pot using a spray

cleaner. If the scratching sound persists, then C16 for both left and right channels should

be replaced. More details can be found in the section "Pops and Clicks" on page 17.

Pre-wiring the Tone Control Switch

This section covers the pre-wiring of the tone control switch. Figure 5 contains a large

diagram of the switch wiring. Cross check the directions here with the diagram.

Prepare the following 6 wires:

1. 6" length of red wire, then strip ¼" of insulation from one end

2. a second 6" length of red wire, then strip ¼" of insulation from one end of this

wire also.

3. 6" length of green wire, then strip ¼" of insulation from one end

4. a second 6" length of green wire, then strip ¼" of insulation from one end of this

wire also.

5. 6" length of black wire, then strip ½" of insulation from one end.

6. a second 6" length of black wire, then strip ½" of insulation from one end of this

wire also.

Refer to Figure 5. Make sure you have oriented the switch as shown in the Figure. The

ALPHA designation, stamped in the metal, must be facing up.

1. Bend a hook in the ¼" uninsulated portion of a red wire, insert it through the

upper BASS 1 hole, and crimp it in place. Solder the wire.

2. Bend a hook in the ¼" uninsulated portion of the second red wire, insert it

through the upper BASS 3 hole, and crimp it in place. Solder the wire.

3. Place the ½" uninsulated portion of a black wire into the upper BASS 2 hole, and

continue with the same uninsulated portion of that wire, inserting it in the adjacent

terminal, as marked by the yellow line in Figure 5. Solder the wire to both

terminals.

4. Dress the wires from steps 1-3 off to the right, keeping them together. A piece of

masking tape around the wires may be helpful.

5. Bend a hook in the ¼" uninsulated portion of a green wire, insert it through the

lower BASS 1 hole, and crimp it in place. Solder the wire.

6. Bend a hook in the ¼" uninsulated portion of the second green wire, insert it

through the lower BASS 3 hole, and crimp it in place. Solder the wire.

7. Place the ½" uninsulated portion of a the remaining black wire into the lower

BASS 2 hole, and continue with the same uninsulated portion of that wire,
