CHOPPING KINKY V1 - ASSEMBLY GUIDE – Rev. Oct 2022
THANKS FOR CHOOSING ONE OF OUR KITS!
This manual has been written taking into account the common issues that we often find people experience in our
workshops. The order in which the components are placed on the board is meant to make assembly as easy as possible.
Some steps are not obvious, so even if you're an experienced DIYer please read the steps thoroughly before starting. You
will be soldering both boards at the same time.
If this is your first project, please read this article before you start assembling the kit:

    CHOPPING KINKY V1 - ASSEMBLY GUIDE – Rev. Oct 2022 CAPACITORS Identifying capacitors can be quite tricky. Codes stated are indicative, please take a look at this guide for help identifying capacitors: http://www.wikihow.com/Read-a-Capacitor Value Code Name on PCB 100n C1, C2,C102, C103, C3, C4, C5, C6, C7, C8, C9, C10, C11, C12, C16, C17, C18, C19, C104,...

    CHOPPING KINKY V1 - ASSEMBLY GUIDE – Rev. Oct 2022 TRIMMERS Solder the trimmers to the PCB where it is indicated by the silkscreen. CAL_A1, CAL_A2, CAL_B1, CAL_B2 POWER CONNECTOR Solder the power connector at “POWER1”, 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.

    CHOPPING KINKY V1 - ASSEMBLY GUIDE – Rev. Oct 2022 LEDs Place the LEDs onto the PCB minding, their polarity, but don't solder them until the front panel is in place. This is the only way to solder them in the right position.
  • Page 6 CHOPPING KINKY V1 - ASSEMBLY GUIDE – Rev. Oct 2022 CALIBRATION We are now going to calibrate the VCA offsets and the internal analog switch to ensure the noise floor is at a minimum. A: VCA OFFSET 1) Turn both channels’ waveform level knobs so that they are at zero.
