A group of 12 neon relaxation oscillators. Each can be switched from an audio oscillator to a audio modullator, or low freq modullator. The coupling of the modullation is adjustable, all are arranged s to couple from an osillator to the one on it's right side, they are aranged or "daisy chained" in 3 groups of 4, 4 going to the left output, 4 to the right output, and 4 that produce low bass that mix to the left and right outs. The buttons are to pulse the each groups power supply to produce "sound bursts" that can sync to music. The "Big knob" moves (slides) all of the pitches up or dowm. from a deep B52 droan, to UFO whines. This is a one-off unit. A 5.1 stereo 24 oscillilator, with all tube voltage control inputs for each channle is in the making.
Beauiful case and front/ layout. And it's sounds very musical.
