I have a couple of plasma balls I could strap to my head. Just need to fina a way to modulate them to electrocute me in time with the music.

Anyone have a link to distortion specs of the Hill design? I've seen the plasmasonic specs and they weren't impressive.

Not exactly portable, huh?

jayphil's page is now defunct but he had a bunch of measurements of the original and his modified plasmatronics--the main change seems to have been adding some acoustic dampening in the form of foam around the plasma cavity, and the result was the cleanest waterfall plot I've ever seen, by far. There's a plasmatronics Google group staffed with owners, and someone there supposed to know jay, so you can ask there for the graphs. Another interesting mod is Nelson Pass', who cascoded the tube-driven current amplifier's output stage with MOSFETs and got even lower distortion (he's actually a member of the group).
Of course, a benefit of the plasmatronics design is that any wanted distortion level can be achieved by simply raising dissipated power/lowering efficiency sufficiently. It's a matter of picking your compromise point.

No less then any electrostatic headphone with an amp. I would be more worried about the very high voltage which is an order of magnitude above electrostatics.

And the voltage you get from walking across a dry carpet is an order of magnitude higher yet--about 20,000 volts.

I'm tired of fearmongering about voltage when it's current that kills, not voltage. Not to mention bringing up a dead horse that's been beat to death multiple times already...

Shhhh don't tell the noobs!!!

I've had so many PM's over the years asking if I'm crazy having all this HV on my head. Still 5kV brings up a number of issues with dielectric strength and arcing.

I don't know why everyone worries so much, just wear one of these under you phones.

A decapitated knight's head???

A picture of King Arthur? Do we need to staple it to our foreheads or to our ears? What kind of paper do we print it on? Photo glossy? Is there an incantation required to give the picture of King Arthur the power to ward off high voltage or is this power inherent in the semblance of King Arthur himself?

It's now an active thread

Some details on the plasmasonics and all sorts of references here https://massless.info/Commercial.html

Yes it's current that kills but good luck getting any current into someone with no volts, and quite a few at that.
