Plasma Loudspeaker Circuit topology, feedback wanted
I'm looking for some feedback on this circuit topology
Right circuit is the ionization circuit. Left circuit is the audio circuit. The electrodes from both sources will be placed in close proximity to one another. Helium will be directed over the electrodes. The ionization circuit will produce 100kV --> 1MV. Once the air is ionized, the electrodes from the audio circuit (~500V) will begin conducting and a stable plasma will be formed. Once a stable plasma is formed, the ionization circuit output can be turned off. Sound will be produced by varying the current through the plasma. Any thoughts?

These new EPC GaN transistors look interesting. 10 EPC1010s operated in parallel for each switch in the DC-DC converter should provide significant current headroom (120 amps @ 200V). However, I believe this may require careful matching of components. Any reason why these wouldn't work?
