Now it’s time to wire the PCB to the panel hardware. As 
there are rather a lot of connections to make, I’ve broken 
this down into two section. It’s worth reading both sections 
before you start soldering!

 

 
Wiring the PCB to the panel hardware – Part I 

I recommend Kobiconn sockets (or clone) for this build. The pads are laid out to make assembly easy 
if you use Kobiconn (or clone of). You can of course use other socket types. 
 
We are going to wire the ground bus first, then work our was across the PCB from left to right (see 
photo). 
 

1.

 

Ground bus:

 using solid core, ground all 6 socket together. The ground bus will enter the 

PCB right at the top of the PCB - see photo below, ground pad is on the far left, marked 

Gnd

2.

 

CV1:

 socket input connects to 

CV1

 pad, socket normalise connects to 

White

 pad. 

3.

 

CV2:

 socket input connects to 

CV2

 pad, socket normalise connects to 

Pink

 pad. 

4.

 

Lag LED:

 the LED’s short leg goes through the pad marked 

LED

, the LED’s long leg goes 

through the pad marked 

+12

5.

 

Lag socket:

 socket input connects to 

Lag

 pad, socket normalise connects to 

+12

 pad. 

6.

 

S/H Out socket:

 socket output connects to 

S&H

 pad. 

7.

 

Rate LED:

 the LED’s short leg goes through the pad marked 

LED

, the LED’s long leg goes 

through the pad marked 

+12

8.

 

Clock In socket:

 socket input connects to 

In

 pad, socket normalise connects to 

Norm

 pad. 

9.

 

White Out socket:

 socket output connects to 

White

 pad.
