Yes you are correct the bottom one isn't a rca connector it's an automotive antenna connector. On the BOL sets the lamp is powered by a rf signal derived from the local oscillator. That's why there's a tapped choke (54) in the circuit. I didn't realize that you were going to be plugging and unplugging.

I was down in the basement in my dad's
