Pin 12 contains the demodulated baseband signal audio. Luckily, this pin
is situated at the end of the IC, and not between two pins. One lead of a
10 k resistor is bent to follow the IC's pin exactly.
Then, the resistor is connected a little to the outside of pin 12 using
a fine tip soldering iron and a minimum amount of solder. The resistor is fixed
to the IC with a drop of glue from a glue gun. This prevents damage to the IC pin when
inadvertedly mechanical stress is applied to the resistor.
