Build it from a kit! This Voltage-Controlled Oscillator is based on the Curtis CEM3340 IC. The boards are available fully-assembled or in kit format. Can be used as a standalone board, put in an enclosure, or mounted behind a modular synthesizer panel (a Eurorack-format panel is available from us, or create your own).
