I have a TV which only accepts RF input and the speaker doesn’t work. I want to use my GameCube on it, but I get no sound. Is there a device that can separate the audio from the video from the GameCube’s RF output? It would also have to output the video as an RF signal (to go into the TV) and the audio as RCA. Does this exist? Thanks.
I can think of a device that’ll do it. It’s called a VCR.
Got a VCR? Try this: connect the game’s RF out to the RF in of a two-way splitter. Run one side of the splitter output to the RF in on the VCR and the other to the RF in of the TV. The connect an RCA audio cable from the audio out(s) of the VCR to your audio amplifier/speaker.
