Well...........there is more than one way to do it. Simplest: Take out the RCA, and wire the BNC to the pads on the little PCB. Remove ferrite doo-hickey, and jump across it. Best: Get a peice of mini 75 ohm coax. RG-187.....something like that. Solder far end of centre conductor (+) to the resistor divider. There are some vias close by. Almost all the vias on the PCB go to ground, but check with a meter. Solder shield (-) to the via. (Go over to Audio Circle........the pictures may help. Maybe not.) Make sense?
