Installing the Treble No-Click Resistors
Prepare a two resistor combination follows for the left channel.
1. Take two 4.7 Meg resistors. Twist one lead of each with one lead of the other.
Each resistor will have one free lead.
2. Form the leads so they can be soldered to eyelets 16, 17, and 18.
3. Tin the twisted leads and the free leads so they can be more easily attached to the
PC board.
4. Solder the resistor leads in place as shown in Figure 6.
5. Repeat the process for the right channel circuit board. You may have to move
some of the wires to the side to avoid melting them, but you should have pretty
easy access to the three eyelets.

Reassemble the PAT-4
Check the 10 added wires to assure that your solder joints are strong and that nothing has
come udone.
The bass pot has 12 wires, 6 original, and 6 added. Each terminal of the bass
control has 2 wires.
The treble control has 6 wires, but the center terminal of both sections now goes
to the tone control switch.
Replace the front panel of the preamp, retaining it in place using the same nuts on
the same controls as prior to disassembly.
Use the previously reserved nut from the Tone Control Switch kit to fasten the
front panel in the area of the new tone control switch.
Attach the knobs to their shafts and tighten their respective set screws.
