Why are plate chokes seemingly black magic? Don't you just want a good decoupling of the PS from the Plate; i.e. lots of impedance from DC to Light and no resonances? How I get that should not be an issue but all teh plate chokes I see are long skinny and sometimes segmented single layer solenoids of questionable wire size. Why wouldn't a really lossy powdered metal toroid with a few fat turns on it work, assuming the inductance was high enough?
