The A/V Troubleshooters
Author: Grayson Evans, Training Reels
This article is a great troubleshooting tip based on the “tool of a thousand uses”, the good old tone generator, tone detector. Everyone has (or should have) one of these in the tool bag. They're typically used to locate cables you forgot to label, labeled incorrectly, or got cut somewhere during house construction.
Next time you have a dead audio path, you can use the toner to work from the audio source component to the final amp, or use the signal generator from the amp and work backwards to the source.
Since we need to make an adaptor for the alligator clips on the end of the tone generator leads to an RCA stye plug, it’s a easy step to add a simple filter/amplitude reducer to make the tone generator signal more amp/preamp friendly.

Photo 3. Ideal tone generator hooked to the audio adaptor with the alligator clips. I built it with two RCA plugs for quick stereo testing.
