For convenience I'll add my latest PM here:
What I find strange is the very low resonance frequency of your device, it's normal to have high consumption at that frequency, my ZPM's consumption is also high when the resonant frequency gets close or below 80 KHz.
What I would do is to double-check that the magnetic fields of the coils are really opposing each other (for example at the top of the core the coils are producing two North magnetic poles oppsing each other) like I do here:
In my ZPMs (I've built two, one is the prototype and the second is a successful replication) as I put more powerful light bulbs on the output the resonance frequency gets lower. So always when I replaced the light bulbs on the output I needed to do another frequency sweep to find the new resonant frequency:
In time I learned what is the zone of the resonance frequency associated to specific ligh bulbs or combination of light bulbs so I didn't needed to make frequency sweep anymore.
But even with 2 x 12V/55W light bulbs on output my ZPM's resonance frequency is still 92 KHz, much higher than the resonance frequency you see in your replication:
And I don't know why in your replication the resonance frequency is so low but it explains the missing low input.
Maybe because there is no grounding connection in the circuit ? Or maybe because of the position of the coils, they're closer to each other than on my ZPM and they somehow influence each other ? I don't have the answer for the low frequency right now.
