Just got a Knight-Kit C-540 tube type CB transceiver, circa 1964-1968. Its in pretty good shape, and actually includes a microphone. Unfortunately, it does not have the AC or DC power cord. I need information, schematic, or Manual for this radio to make up my own power cord (It has an 11 pin jack on the back.) Cant find any info online except for pictures of the radio. Does anyone know anyone that has this radio or information? Thanks, Marvin
