I must admit, I do not know the correct position to place the AC cap,
but my testing has shown that a 6.8uf AC cap across the drive coil pair reduces amp draw by 25% and
NO reduction in RPM.
....

Hi Penno,

I believe the placement of a capacitor in parallel with two series drive coils is the right place if you wish to further test its input current reducement effect: the cap forms a parallel LC circuit with the series two drive coils and in case you choose a cap value that happens to create a resonance at or near the RPM frequency then this LC tank is going to have the highest AC impedance, hence the input current would be the lowest versus a no cap condition.  The reactive currents inside the LC tank will still be high (loaded Q times as much as the input current to the tank) so this explaines why the RPM can stay the same or very nearly the same.
OF course we do not know if Romero had any such cap at the drive coils but this is a kind of modification that can cause no harm...

Also, a suggestion for those using Romero's driver circuit with the Hall device and the bipolar PNP transistor: a series resistor could be inserted between Pin 3 of Hall output and the base electrode of the transistor to reduce input base current to the transistor,  as Romero showed, the 12V goes directly to base-emitter junction and the saturated Hall ouput transistor's collecter-emitter junction without any current limiting, so a resistor of any value between 470 Ohm to up about 1.5 kOM will limit nicely the input base current, hence the total input current to the driver stage.
This way a further 50-150mA reducement could be had without RPM change. The inserted resistor value needs testing of course.

One thing you surely can understand without any translator - "selfrun" only when SUPERCAP
