Its time to install the vactrol. A vactrol is made from an LED and a light sensitive resistor that are 
sealed in a light proof casing. The LED is on the side of the vactrol with the shorter legs. Because 
LEDs are polarity sensitive (polarized) it must be installed in the correct direction. Locate the 
white dot on the side of the vactrol 

 this is the negative pin on the LED inside the vactrol. The 

negative pin marked with the dot must go into the hole marked with the word DOT. Refer to 
pictures. When happy that its installed correctly, solder it into place.
