You Can DIY! Building a Null Tester Device

Now, what's a Null Tester? The Null Tester sends the same audio signal through two paths, then it electronically subtracts one signal from the other to obtain the difference.

Obsessed with settling this dilemma, Winer designed a Null Tester device that compares any two signal wires and reveals their difference to a level below -110 dB.
