In the previous video, • Using Tektronix CSA803... , I tried to find a break in the speaker cable using the time-domain reflectometer. Having figured out roughly where it was, I've chopped about 40cm off the end of the cable and refitted the plugs. Will it work now?

Good stuff. Back to video conferencing, the devils spawn of lockdown :)

Another neat way to find such faults is to simply pass a dc current through the cable and observe it with a thermal camera, or even just feel where it gets warm. For greater effect just increase the current until it smokes at the location of the fault :-)

I've used that technique to find shorted components on a PCB. If you get the current right, the offending part will either catch fire or desolder itself and drop off the board...
