I have recently acquired the Knight-Kit C-540 tube type CB transceiver , circa 1964-1968. Its in fairly good shape, with a microphone intack, and a nice front panel. It did not come with a AC or DC power cord that plugs into a 11 pin socket on the back of the radio. I need a schematic (or even better, a manual) that can tell me the AC pins to use on that 11 pin socket. I cant find anything on the internet other than some pictures of the radio. Can anyone help? Thanks, Marvin
