How to Troubleshoot an Amplifier with NO SOUND (Signal Tracing in 4 Minutes!)

In this video we discuss signal tracing in brief. Signal tracing is a technique used to find out where a problem is in the signal path of an amplifier. One must know the basics of how tube amplifiers function and how to read schematics. I am a beginner and I was able to build a simple probe that allowed me to use this great technique.

What you need:

1 Amplifier that Needs Repair (for troubleshooting)
1 Bench Amplifier (for signal tracing)
Gator Clips
A pencil
Wire (Gauge 18 or thicker preferred)
Duct Tape
