BEFORE YOU GET STARTED
Before you start the construction of this DIY project, make sure that
you have basic soldering skills and that you can identify electronic
components. If it is your first time in soldering, there are several tuto-
rials on youtube, that will help you :)
It would be easier and helpful for you to work on a big desk, so as
to have plenty of space to work on. Also a room with an open win-
dow would be perfect when you solder.
Before you start the soldering process, make sure you have all the
components needed and noted in the BILL OF MATERIALS SECTION.
Please note that we might have included more components than
needed or (hopefully not) less. It would be very helpful if you count
all components before starting the project, but without removing
these from their bags .

Page 18: Step 7 - Test, Ics, Tune & Finalize
What you need to do, is to power up the module and measure that it gets the correct power supply, before you install these last senstive ICs. So, connect the antiphon (without the front panel) to a eurorack compatible power supply connected with the ribbon cable provided. - Page 19 Now, remove the screws that hold the bottom board and unplug the two boards.

Now, you need to check that everything works, and then tune it. To do that please check on our online YouTube Channel : http://www.youtube.com/c/Dreadbox-synths...
