I am replacing the inductors from a pair of L55's. It has 4 leads coming from it. Does anyone know what the additional two leads are? Are there just two wires off of the inner lead and two off of the outer? Would both measure the same? Since this inductor is still attached to the crossover, I can not get an accurate Mh measurement and do not know what value of air core to replace it with. Thanks in advance, Zipplok.
