Erica Synths DIY Polivoks Voltage Controlled Oscillator uses the core of the original Polivoks VCO, but has plenty of modifications to adjust its performance to modular synth standards. Also DIYers can make their own modifications described in the Build manual. DIY kit, as all Erica Synths Polivoks modules, comes with a set of the original Russian ICs and transistors in three options: PCB (2 layers, 95x97mm) + rare parts (including copper sheet to make RFI/light shield for transistors :) ), PCB + rare parts + panel and full kit with all parts included to build this exciting module. Polivoks had two slightly different VCOs, therefore we made a PCB that is configurable to build both VCOs. WHEN ORDERING ONE VCO WITH A PANEL, AT THE CHECKOUT SPECIFY IN THE COMMENT, WHICH PANEL YOU ARE INTERESTED IN! VCO1 - with X-Mod option, VCO2 - with detune option.
