I guess that the secret is the operation of the chokes in the sense that they have a very important impact in the technology. I think meyer added a variable resistor to tune the coupling between the coils or not limited to that! In the logic that we want to flex the molecule maybe I believer the resistor is in series with the wiper coil or the lower value coil and my best guess is that is there for directing the current thru the chokes. so he maybe uses only one diode.. the resistor will mess up with the collapsing of the field too. If allows faster collapsing fields.
Perhaps is good enough one diode since the wiper choke will mimic the voltage of the first choke, giving the the cell already a pulse of voltage during the initial pulse. You see? Although its charging each tube positively the other will be charged to a potential whatever and the important is that the electric field is there acting causing no harm consuming no power and forcing the current to flow in the circuit formed.
Is kind of genius ! very xxxxxxx amazing! I hope i'm right... I got that because i understood that meyer started over from tay he principle but he wanted to get around the high cost difficult processing of materials and he wanted it to be able to be done in the garage.
He wanted to use just couple of electronics and raw materials like copper wire, acrylic, ferrits, stales steel tubes, ferrite cores, delrin material, and plenty fresh water.
Think about why he used a very think acrylic tube?
