4U011 - Dual VCA

4U adaptation of the Yusynth VCA; this version is really close to the original - all credit goes to Yves Usson.
This version is AC only and misses the LED driver part of the circuit; two identical circuits are present on the board.
For more information about the circuit, please visit his amazingly detailed website.
