From the project

A dual-flyback setup that can produce stereo audio through plasma arcs.

Two CRT flyback transformers are driven by a 555 oscillator based circuit, The frequency of these oscillations is modulated through an audio input, from a laptop into an RCA jack. However, by splitting the AUX output into left and right RCA, we can get stereo output. This should produce long arcs at a 24V primary (base, should spike higher). To the grounded metal case of the power supply (inspired by Franzioli Electronis).
