Making a Modular Synthesizer - Part 1: VCO and Power Supply

I started my synthesizer project by making a power supply. I used a Mean Well RT65B and a DIY bus board to turn mains electricity into usable -/+12V DC. For my first VCO build I used the CEM3340 voltage controlled oscillator chip and schematics which I've found on lookmumnocomputers website: https://www.lookmumnocomputer.com/pro...
