Re: [TCML] Musical Tesla Coils (plasma speakers on steroids)

The Amplitude Modulated Ham Radio guys have been playing with high 
fidelity solid state pulse with modulation of RF at that power level 
for years.  I bet some of their technology will cross over to your 
needs.   Try a Google search.

That kit is nice and cute, unfortunately, it's not capable of pumping 
the amount
of power I'm looking for.  I would like the experience of constructing 
my own
coil.  The biggest problem I have at the moment is "How do i take an 
already
great SSTC design and make it sing?"  There are so many refined SSTC 
schematics
out there fully capable of 500 watt plus power levels.  However, I am 
not sure
how one would go about turning any of them into audio modulated 
systems.

This is my idea so far:
Design a 300V Hexfet class AB amplifier using 1000 watts of power 
mosfets.  Take
the signal from my mixer, send it through a 1:1 audio isolation 
transformer, and
ground one leg of the transformer on the output side so I have only a 
positive
biased waveform.  I can use that waveform to feed a low distortion 
MOSFET drive
chip.

Lastly, I will take my now audio modulated 1000W 300V signal and power 
my SSTC
directly with it.  Resulting in a crisp AM discharge with a class AB 
quality.

Dose anyone see a problem with this design?
