Trim one lead of a 220 ohm 1/4 watt carbon composition to about 1/4"
Attach the long lead to the upper hole of terminal 19
Attach the short lead to terminal A4 so the body of the resistor is very close to terminal A4.
Solder terminal A4 and the upper hole of terminal 19.
Be very careful not to overheat the relatively delicate carbon composition resistor at terminal A4.
