This circuit has two pots, one for adjusting the primary coil voltage amplitude and another for adjusting the pulse voltage amplitude of the pulsing during the 'Gate' time.
There are four options for driving the primary coil.
1. Gate time high-Current flows through primary coil during gate time
2. Gate time low-No current flowing through primary coil during gate time
3. Variable pulse voltage amplitude during gate time (via P2)
4. Continuous pulse frequency
Both high (resonant) and low (gate) frequencies are provided by a FeelTech function generator which provides independent frequency, duty cycle, and sweep functions. The drive circuit, function generator and VIC coil are all powered by a Ryobi 18V battery and a programmable power supply as seen in previous videos.

Explanation of the circuit I made to get variable amplitude pulsing during the 'Gate' time. In this video I stated I made this circuit for the PLL but forgot I actually made it after Ronnie (GPSSONAR) mentioned it was necessary to get the cells working.
I'm going to be building this circuit again and I'll start running tests on it, once I get it working I'll probably make a PCB and if all goes well I'll share it here and on the forums.
I forgot to mention but for the HF and LF pulsing I use a dual channel frequency gen that has adjustable duty cycle and bias as well as a sweep function. With this setup the circuit is adjustable in every way needed.
