Transistors: 

4 – 2N3904, 2N5088, 2N2222, or similar  

 

 
 

 
Potentiometers:  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.
