A*B+C v1.0 - ASSEMBLY GUIDE – Rev. July 17
POWER CONNECTOR
Solder the power connector at “POWER”, ensuring it is facing out from the edge of the PCB.
The small arrow on the connectors must be on the side with the thick white line.

FEMALE PIN HEADERS
Place the female pin headers over the silkscreen markings at positions “CONTROL” &
“CONTROL1 and solder.
SPACERS
Secure the spacer onto Control PCB (through the hole with silver outline) with the main body
of the spacer on the component side, and the nut on the opposite.
FRONT PANEL COMPONENTS MOUNTING TIPS:
Now we will proceed to mount the jacks, and potentiometers. This part of the assembly is
CRITICAL. Please take your time and read the following instructions carefully.
These components must
NOT
be soldered until they are placed on the PCB and fully attached
to the front panel.
There are two reasons for this:
•
The height of the panel components are not all the same. Because of this, if not
attached properly before soldering, they will not stay properly seated against the panel.
This might cause mechanical stress reducing their life expectancy and in the worst case
cause them to break.
•
The second reason is that it is very difficult to align the components to the holes if the
panel is not positioned prior to soldering. In the case of the LEDs, they are almost
impossible to set to the correct height without reference to the front panel.
