I'll probably use one per channel and step up the voltages somehow, I'm thinking using the pulse compression method or just using a MOSFET. Once I go about 600V or so, I'll have to ditch the MOSFET and use something else. If I wind up trying to replicate the original, I'll probably have to use the 300V pulse with RF transistors for the high frequency stuff. But right now I'm sticking with a bias coil to keep the frequency requirements low. I hope that Spherics really meant 300V and not 1KV or higher per the AVEC, that voltage requirement is hard to meet.
For the AVEC (next on the list), I'd probably focus on using a saturable reactor chain to boost the voltage each stage. Each stage would also compress the pulse somewhat, according to the research paper I read. The math was quite complex however, and I'm not sure what repitition rate I could get out of such a setup. I'm hoping that the bias coil in these setups reduces the frequency requirement substantially.
Another way would be the transistor stack with my 4kv DC-DC converter and something to control the pulse width.
He said "if the bias coil is fed high current and high volts you should get pulse rates as low as 3khz", so I'm assuming "high amps" would mean around 5 - 15? That seems quite high. Voltage wise, I didn't think it mattered too much, but I'm not certain at this point.
