I wanted a VCA module for my modular synth setup. I was going to buy either a Mutable Veils or an Intellijel Quad VCA.
But then I discovered the Vncursal. It’s a 6 VCA in one module at just 8HP.
In this post I’ll go over the building of the kit, followed by calibration and installing/testing in my Eurorack case.
The kit uses all through-hole components and is fairly easy to build.
The design is tightly packed using all through-hole components
Main PCB complete
The second PCB holds the jacks, pots and LEDs
35mm deep
4hp wide
Install into rack
Test
Calibrate

Conclusion
If you want a decent quality linear VCA the takes up minimal rack space, I think this is a good option. It’s straightforward to build but you can also buy it as a fully assembled module.
