Korg NTS-1 Custom Case Mod

NTS-1 is awesome little digital programmable synthesizer kit made by Korg. Build it, tweak it, connect it; a world of synthesis at your fingertips! Korg It has large potential with added plugins and has powerful digital effect processor. But the self made pcb enclosure design and small SMD audio, sync and Midi connectors are to flimsy and tend to brake a lot. I wanted to have full size 6.35mm audio jacks and Din-5 Midi sockets to be able to use this synth in my setup, so I need to make my own sturdy case. I had some wooden box leftovers

I have unused laptop power brick that has around 16V and 5A on the output, use couple of power regulators to get down to 12V, 9V and 5V. I used

Drill hole for the resonance pot between decay pot and power switch. Install 1kΩ pot and solder leads to the ends of R39 smd resistor on the PCB. 5V power regulator is added on the other side of the PCB, it’s middle (GND) and right (OUT) legs fits to the battery wire holes.
