This is the PCB and PANEL set to build a 10 Oscillator bank of the Megadrone, this item can be powered with either eurorack style power or just standard 12v adapter. So you dont need a synth power supply to run this item! Its a very large PCB and PANEL set measuring 40cm x 20cm, its a big old chunk of material!
