Thank you for purchasing a Shakmat DIY kit !
We spare no effort in our kit packing process to prevent any mistakes or
missing parts. In this document as well, we do our best to describe the assem-
bly process in the most practical and comprehensive way. If by any chance
there is a missing/damaged part in your kit or if you have any suggestion, feel
free to contact us via shakmat.com.
The assembly process will be dramatically simplified if you follow the order
defined by this building guide. We tested various orders of steps before finding
the most convenient, and the one presented here is the best!

4. PCB stacking
We begin by joinning and solder the two PCBs together. Be careful during this
step, if you solder every pin and the PCBs arn’t well aligned, you will likely not
be able to correct it. To stack the two PCBs together, headers are used.
There are two pairs of 8 pin male & female headers and one 6 pin pair.
First assemble all the headers with their mate. Then place the female part on
the bottom PCB and the male part through the top PCB. Then assemble the
two boards toghether and proceed to the soldering.
You will first only solder one pin of each header. It is important that you firmly
hold the two PCBs against each other while soldering. There must be no gap
between the PCBs and the header’s black plastic part between them.Once
you’ve soldered the first point of each header and check the alignment, you
can move on and carefuly solder the remaining points.

5. Top PCB assembly
Disconnect the two PCBs and proceed to the
following steps with the top PCB only. Place
and solder the 9 jack connectors. Be sure to lay
them completely flat on the PCB before solde-
ring. If those jacks aren’t perpendicular, the
front panel will be very hard to mount.
If one of the jacks is not perfectly perpendicular
with the PCB, you can reheat the pads and
push it down with your thumb to re-align.

Place and solder the 3 slide switches. Be sure
to lay them flat on the PCB when soldering.
We recommend you only solder one of the pin,
check alignement and if you are satisfied with
you placement, solder the remaining pins.

Before soldering, you will have to cut a little
metal piece off the top of each potentiometer,
as shown in the picture. This little stud prevents
the front panel from sitting properly. Use some
small & sharp cutting pliers for this task.
Then, place the 3 potentiometers on the PCB.
Mount the front panel and tighten the potentio-
meters nuts lightly (this will ensure a proper
placement of the pots) and then solder them.
Once you have soldered everything, remove the
nuts, the front panel and proceed to the next
step.

Place the power header, the short pin side in
the holes and solder only one of the pins.
Check the alignment and correct if necessary.
Then, once your component is upright and flat
on the PCB, solder the remaining pins.
