PCB V1.2

01. BUILD NOTES
Before you start building look through the build manual
so that you’ll be familiar with the building process and
you won’t run into any surprises!

02. BUILD
00. Orient the PCB as seen on the left
01. Solder the V2164M VCA in place
(oriented to the top)
02. Solder the five TL072s
Look out for their orientation!
03. Solder the single LM4040 10V IC
04. Solder the single LM4040 2.5V IC

02. BUILD
05. Solder the two 1n5819 diodes
The marking should be on the left!
06. Solder the single 100 ohm resistor
(This one sets the jack LED brightness)
This is optional depending on if you want the jack
LEDs or not.
07. Solder the eight 510 ohm resistors
08. Solder the two 1.2k resistors
09. Solder the single 3.6k resistor

02. BUILD
25. Solder the two single pin headers
These are optional depending on if you want to chain
this module with other DVCAs.
26. Solder the single 1x2 pin header
You could leave this if you don’t want the jack LEDs.
27. Solder the 2x5 pin power header
28. Flip the board
29. Place the pots, LEDs and jacks. Now put on the front
panel and tighten the nuts on the jacks and pots.
Align the LEDs in the holes as you like them. Solder!
You are done with building! Congratulations!
