HISTORICAL BACKGROUND:
General Electric's Mobile Radio Department in Lynchburg, Virginia, manufactured and supported professional two-way communications equipment used by public safety agencies, commercial operators, and industrial organizations. During the era of discrete transistor receiver design, 455 kHz intermediate-frequency transformers were essential components in tuned receiver stages, providing frequency selectivity and coupling between circuits. GE service documentation identifies part number 19A115711P6 as a 455 kHz transformer with a comparable TOKO PEFCN-14733-CX12 design. This Japanese-manufactured component retains its original GE service parts packaging and represents the specialized replacement components stocked for maintaining professional communications equipment.
