DIY Build Instructions – KOSMODROM CORE [v 1.2 PCB SET]

First of, thank you for your purchase of the KOSMODROM CORE DIY Kit. If you are a DIY Synth novice, you have selected a great module to
strengthen your skills. If you are a veteran [or, as we like to say at Tsyklon Labs - “Hero of Synthesizer DIY”], then this kit will be super fun
and you will likely have it assembled in short order. Also, if you are not familiar with component naming, please check out page 14.

First, let's make sure that you have everything on hand before we heat up the iron. The tools you will need are as follows:

- Soldering Iron [if you have both a fne point and a chisel point, that will work well] and Solder
- Wire Cutters
- Needle Nose Pliers
- Wire Strippers that can strip 24AWG wire
- 2.5mm Allen Wrench or Small Phillips Screw Driver for tightening M3 screws on PCB Standofs
- 10mm Deep Well Socket for tightening Potentiometer nut and 7mm for Toggle Switch nut
- Knurled Nut Tool [Xicon 382-0006] or 8mm Socket for tightening Jack nuts

Verify that you have the following parts [if something is missing, contact us right away for replacements – diy@tsyklon.com]:
