Ok. Let’s try this again…RCA 9TC240 Alignment

So my brain needs to flush all this out to be able to understand it. It’s just the way facts have to get processed before I get it. So when a signal with different frequencies goes through a circuit and you are trapping one or removing one with a trap coil, that coil, by moving an iron slug to the appropriate position within a winding will resonate at the desired frequency matching the signal to be filtered out. Is it the coil in circuit that is resonating at various frequencies including the one to be trapped and that energy is dissipated by the fact there’s an adjacent coil at just the right “stimulateable” resonance that essentially sucks the frequency energy out of the broader signal? It’s like a filter that hijacks the undesirable frequency out because it’s tuned to “pick it up” from the broadband family of frequencies passing through? Or am I lost somewhere in the asteroid belt!
