Classic PAiA 9720 VCO Module Retrofitted for MU Format

This is the PAiA 9720 moved from traditional FRAC format to MU. The panel is a Synthesizers.com Q133 Quad Blank Panel. Silkscreen design was originally done by GuitarFool.com then modified slightly. 1/8" jacks have all been replaced with 1/4" jacks and mini-knobs have been replaced with 1" skirted knobs. Like the original version several connections are normalized including the the 1V/Oct port from oscillator #1 through the Glide circuit with oscillator 2. The modulator output is normalized to the pulse width of oscillator 2.

The board has also been modified slightly to accept input from a +/-15V QPS1 Power Supply.

The modulation LED has been changed from red to blue because blue is cool and so is this modification.
