Knight-Kit C-540 tube type CB transceiver

Knight maybe had a uniform wire hook up for plug connections on most CBs and I saw this one so may be helpful for comparison. Knight C-11 model.

I agree on tracing out the wiring from that multi-pin jack on the back of the set. A lot of those early tube type CB radios had a 117V AC line input for Base Station use as well as a 12V DC input for mobile. The 12V DC supply will likely use either a single vibrator unit or (2) large power transistors mounted on a heat sink. There may be a single combined power transformer or two separate transformers. The primary winding for most 117V transformers will have black insulated wires coming out of the coil winding assembly (cloth covered or vinyl plastic). This should indicate the 117 Volt AC input line. Trace the wires back from that 11 pin jack (socket) and see what you can find. Also, I am wondering now if that socket is an 11 pin Jones type or a round 11 pin keyed type (resembles an octal tub socket). Good luck.

You may have to show a handmade schematic from the pins to each internal wire connection.
Of course some will be obvious, two wires to the primary of the power transformer. Two wires for the RF (one being ground.) You may have better luck looking for CB Club forums for advice.

I have acquired  a Knight-kit C-540 tube type CB transceiver , circa 1964-1968.  it did not come with the AC power cord that plugs into an 11 pin jack on the back of the cabinet.  I will have to wire my own, but I need a schematic (or manual would be better) to wire one up.  I can find nothing online except pictures of the radio.  Thanks, Marvin
