"Compact 6HP VCO for Eurorack Modular synthesizers

DIY - PCB AND PANEL ONLY

This is a compact Triangle Core VCO. You can install your classic CA3080 OTA chips or use a modern LM13700 instead. The PCB has the option to use either chip.

This VCO has been shrunk to the minimum size possible so you can maximize the remaining space in your rack, while packing in a wealth of functionality:

Triangle, pulse and sine wave forms
1/V octave input + variable Linear FM CV and variable Exponential FM CV
Adjustable pulse width and variable PWM CV input
6HP Eurorack with our panel
This is a low component count project so you can have high quality VCOs in your rack with minimum expense.

Build it yourself - This is a set of one high quality PCB and front panel ONLY for users who want to purchase their own components and build their own module. Some product photos above show COMPLETED build.

This module will fit perfectly into a 6HP Eurorack space.

Comprehensive manuals, parts lists and component shopping carts are provided in the documentation link for building, testing and using the module."
