Thank you for purchasing your EURORACK DIRT filter Kit, please follow the instructions to ensure that you have a fully functioning unit.  ATTN:  Please follow the BOM and these instructions and don’t populate from the PCB alone. Also sometimes we cannot get the exact pictured components, so please look over your parts and check the codes first.  Let’s get started!

RESISTORS & DIODES

First, start by populating the resistors and the diode, as shown below, then turn over on a firm surface to solder then clip your leads.  Diodes are polarized components so you must match the black stripe on your diodes with the white stripe on the PCB silkscreen.

Socket, IC, Power Header and Transistors

Place the IC Socket  in place by aligning the notch with the notch graphic on the PCB Silk Screen. Turn over and solder.  Then place the 16-Pin Power Header by aligning the notch on the header with the notch on the PCB Silk Screen, turn over and solder.  Next add the transistors by matching the flat side of the transistors with the flat side on the silk screen.  Turn over, solder and clip all leads.

CAPACITORS

Place the capacitors in place and solder and clip leads.  Make sure you orient the electrolytic capacitors in correctly.  The longer lead needs to be inserted into the hole that has the “+” marking near it.

POTENTIOMETERS & JACKS

First trim the alignment nub off the pots, as this will create a ‘wanky’ front panel.

 

Next add the Pots and Jacks, solder then trim.

FRONT PANEL & KNOBS

Add the front panel to your unit and tighten down the nuts carefully and do not over-tighten.  The knobs can now be added and aligned as shown below.

 CONGRATS!  You are now done with your project and can test the unit in your eurorack system.  If you have any questions or need help debugging, please first refer to our troubleshooting guide BY CLICKING HERE.  If this gets you nowhere, please contact us by email for support.  Thank you again for purchasing your kit from Synthrotek!
