Hey as some of your comments in the vid suggest, do you have a kit for sale? I'm mainly looking for a PCB. Nice work, pretty clear sound too, especially the highs!

If i were to ask for the schemattics i would say,"Hi. Would you mind sharing the schemattics with us because that is one of the coolest things i have seen in a long time." Be polite to people so other prople can be polite to you.

Absolutley ! - I've found above 115kz (with the ferrite material flybacks use), the output drops suddenly.
The commercial units all use RF air-cored transformers and sizeable horns, to acheive a decent volume.
Perhaps an electrode-based disharge with an air-cored transformer might be the way forward ?
The large modulated TC's I've seen, do perform OK, but seem to produce a great deal of corona noise....
the next step up this would be some type of air cored transformer (generally a Tesla coil running in quasi class E) running at 4+MHz At this point the arc becomes silent and very high frequencies can be produced

It is and it still will be. All they are saying is instead using a flyback transformer and have it arc from it's hv lead to it's ground lead you would have a air cored transformer arcing from it's top lead to it's bottom lead kind of like i bipolar coil.
