Pots ‘n’ sockets PCB

 

 

1.

 

Solder all resistors 
 

2.

 

Place all sockets on the PCB, 

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

ground pads, 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.  
 

3.

 

Place all pots and the switch on the PCB, and fold over their mounting tabs at the 
rear of the PCB, then place the panel over them. This will assure that they are 
correctly positioned. Flip the whole lot over and solder the pots into place. 

 

4.

 

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

 
 

 

 
 
Note: Not all pots and sockets are equal in height. Providing you use the ones in the links 
provided, everything will line up perfectly. 
 
Make

 

sure that you plug the 

Main PCB

 into the 

Pots 

n

 sockets PCB

 the right way around 

 

Frequency Central logo should be the right way up.
