This customer needed a pair of Envelope Generators for his system which are difficult to find. I converted a pair Synthesizers.com Q109 Envelope Generators to a single panel Aries format.

I had to use smaller knobs and 16 mm potentiometers to fit two in the panel.

Assembly was straightforward. I had to replace four of the cables to reach the top PCB. I built a daughter card to generate 10V envelopes.

Standard ADSR operation.
