AUX input jack for 67-72 AM radio - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Couple of thoughts:
1. A cap soldered to the case sounds like a tone control, rather than volume. These are stacked pots, right?
2. The easiest way to figure this out is with an oscilloscope. I have also used a set of headphones with one side tied to gnd and uses the signal lead to poke around and follow the signal path. You want to find the input side of the volume control.
3. I wish that had an AM/FM to figure this out. :-)

Maybe someone else has figured this out.
