"Even coaxial would be OK, if the recording device in question outputs on channel 3 or 4 via coaxial, but these days most only use coaxal as a pass-through for the cable / antenna signal."
"There was also a coaxal power jack and diode (now shorted out) added for testing from a wall transformer which are not required and are not shown on the schematic."
