This has been asked before, I'm sure, but anyway......there's an RCA jack on the back of my 41-296 (41-285 chassis). There is no band position for it, though. The signal passes thru a cap and then straight to the center lug of the volume control. To test it, I used the ear phone jack of my transistor radio. It works perfectly, regardless of where I'm tuned on the dial. I'm used to installing iPod jacks that cut out the radio, so how does this work?
