Hello Friends! I had just begun to refurbish the Sparton 581X, when on closer inspection, the L1 "IF Rejection Coil" was mostly consumed by a mouse. I have no idea what an IF Rejection Coil is (see schematic link below) or does, and I think it may be made of unobtainium. Has anyone run into this item? Where to find one? Looking at the schematic, I'm inclined to believe that the radio will work without it by attaching the antenna directly to the primary of L2. The schematic also shows a little 'gimmick' coil in the same area. The mouse probably ate that too, along with parts of the wax caps. I hope he/she was happy with their snack. Thanks, Joe
