SNAP OFF THE SMALL TABS ON THE TOP OF THE POTS OFF WITH A 

PAIR OF NEEDLE NOSE PLIERS. IF YOUR POTS HAVE COVERS, REMOVE THEM BEFORE 
CONTINUING. YOU MIGHT HAVE TO CUT A SLIT IN THE COVER WITH A BLADE AND 

USE A SMALL SCREWDRIVER TO GET LEVERAGE.

Your kit will come with mostly 1/8 watt resistors. If you receive 

¼

 watt resistors, 

simply bend them so the body is vertical on the PCB. Below is an example
