TriNegistor, a Triple Negistor oscillator noise box

-- ref. 2010

This box I present here is a triple negistor oscillator. This is basically a noise box I use to make sounds.

The orignal schematics cames from Charlie Barth trinegistor, you can find it here

I just change some components and add a few switch to his schematics.
First of all, what's a Negistor? It's a a NEGative dIfferential resistance oscillaTOR, it's an oscillator built using his NDR effect. The negistor I use it's build using a 2N2222A NPN transistor wired in reverse mode. Please find more information here:
The tri-negistor is built putting in series three negistor oscillator.
