I checked my radio serial #05A10106 and it appears to have this mod
both in the schematic and on the IF/AF board. It is labeled C25.
WARNING! WARNING! The labeling of coax jacks J54 and J56 are reversed
on the IF/AF board itself. The labels on the coax is correct. So if
you remove the IF/AF board you must connect coax 54 to J56 on the
board and coax 56 to J54 on the board. I would assume this applies
only to newer IF/AF boards. Mine is labeled Rev C.
