Pots ‘n’ sockets PCB

 

1.

 

Solder all of the toggle switches. Please note that there are 2 

on/on

 switches and 4 

on/off/on

 switches, the lower 4 switches are all 

on/off/on

 type. The back of the PCB 

is your friend here, as it states clearly either 

on/on

 or 

on/off/on

 for each switch. 

2.

 

Place all sockets on the PCB, 

making sure the ground tabs line up with the PCB’s 

ground pads 

 be careful because there are two different orientations - then place 

the panel over them. This will assure that the sockets are correctly positioned. Flip 
the whole lot over and solder the sockets into place. Use cut off resistor legs to 

connect the sockets’ ground tabs line up with the PCB’s ground pads.

 

3.

 

Place and solder all 16 poteniometers. 

4.

 

Cut female headers to size and solder them into place. Make sure that they stick out 
of the bottom of the PCB. 

5.

 

Put all 26 LEDs through their pads. Present the panel to the PCB, flip the whole lot 
over, make sure the LEDs stick though the holes in the panel, solder in place. 

 

 

 
 
All done! Go play! Expect confusion!
