    on/off switch, as shown in Figure 8-11.


12. Solder one 8" wire to a variable capacitor lug and solder one 8" wire
    to the metal body of the variable capacitor, as shown Figure 8-11.

The lugs are electrically connected to the stationary plates of the capaci-

tor, and the metal body is electrically connected to the rotating plates.

13. Solder 8" wires to each of the three potentiometer lugs, as shown
    Figure 8-12.


14. Solder 8" wires to each of the two speaker lugs, as shown Figure 8-12.
