I finally figured out the wiring on a vintage King KX170B

Pulled a beat-up King nav/com from a junkyard plane last month for a side project. Turns out someone had jumpered the audio lines wrong, which explained the weird static. Got it cleaned up and working on my test bench with a basic signal generator. Felt pretty cool to bring a piece of history back to life. Now I'm hunting for a cheap scope to make these fixes easier.

That audio line jumper fix is neat. What kind of signal generator did you hook up to your test bench?

Signal generators are often overkill for audio fixes (just my take). A basic phone app can handle most tone generation needs.
