pt6 Hartley / SEC Exciter, Inductive and Capacitive Tuning

this experiment is based on bakupcpu’s video, but using B&W inductor coils, adjustable ferrite core, and adjustable topload capacitance via aluminum plate. Here the load is between the plate and open ended long wire, LEDs are facing forward and backward in even strings(anti parallel) 9 forward, paralleled to 9 backward. And if it were grounded fully, as Eric Dollard has said, (for example) ” if I closed the circuit at 2000 ohms, we would only have a regular SWR of 1, and no resonance… but I chose to leave them open”
