Model A (AS662D dual VCA)

Dual VCA built around the AS662D chip

Inspired by SH101 sound and some stuff on modwiggler. This project is DIY and CC BY SA. Some sound clips, schematic and gerber files here: https://maffez.com/?page_id=2892

This VCA is AC coupled but you can easily turn it into a VCA that is also able to process CV signals by soldering wire in place of the four 10uf capacitors (C C2, C9, and C10).
