[Hallicrafters] SR-400A filter

[Jim Liles]

Looking for the filter for the SR-400A or a parts radio.  The filter that was in the radio had a spur outside of the bandpass allowing carrier to pass in upper sideband mode and signals nearly out of range of my old ears in lower sideband mode.  Disassembled it and found six large and two small crystals and a kluge of other components.  The center freq for the filter is 1651500 not the 1650000 as in the SR-2000 and SR-150 and is a different physical shape.  Replaced one crystal and resoldered grounds but destroyed the case in so doing.  Any help would be immensely appreciated.  Kindest regards Jim K9AXN
