As mentioned above, I have tried to use coils on ferrite formers in a series- / parallel LC configuration on several places in the ZPM circuit as i did with the air coils, but similar results were seen being:
A slight resonance (sine wave like signal on the feeding voltage / current) in some cases (positions) causing the input current to decrease slightly, but it also causes the load bulbs to dim, which is understandable and expected.
So i think i have exhausted almost all possibilities to create the "effect" as shown by Fighter his ZPM being 2x 12V 55W bulbs (100W) brightly on at a certain high frequency (600kHz) while the input current drops to almost zero mA (creating the illusion of an almost infinite COP).
The closest i came to this "effect" was to have resonance in the circuit (by using an external filter to the PS) showing the PS decreasing its current to almost zero
But it also showed the load bulbs going off due to less or no input power
The issues i have with Fighter his ZPM are that:
# no one of the several replicators has been able to replicate the above-mentioned "effect". (sure there are replicators showing decreasing input current like me, but not with the load bulbs staying brightly on)
# Although Fighter has documented his ZMP experiments rather well, the key measurements and data are not provided or are deemed inconclusive, like the alternative input power measurements.
# there are strong indications of an instable environment (grounding?) or even feedback / oscillations in his circuit by looking at the fluctuating current on the PS amp. meter and the slow oscillating (few Hz) of
the bulbs in some cases.
# a very big problem could be the used FG (feeltech-fy3224s) who seems to have a problem in that it is not very well isolated from mains power see here:

https://www.youtube.com/watch?v=BqxA4HRYjVgThis last problem (possible 115V AC on the BNC plug) could very well also cause the reported quick heating of the MOSFET.
Anyway, Fighter himself is the only one able to address these raised concerns by using an alternative power source (batteries preferable), a different FG and proper alternative input power measurements.
But due to time constraints he seems to have, i do not see that happening any time soon.
So i officially declare my ZPM replication attempt as failed and i will shelve my ZPM device next to all my other failed attempts to replicate a claimed overunity device until new insights become available.
All these failed replications sounds not very positive, but if they were not failing, that would mean i had succeeded in replicating an overunity device, but as we all know, such overunity devices are not existing
yet in the public domain.
That's why we are here for.
