Broken Amp No Sound? Use a DIY Signal Tracer

In todays video I show you how to use a guitar amp signal tracer tool that I built for finding faults and failing components in broken guitar pedal and amp circuits with no sound. Using an audio signal tracer can help make a complicated circuit problem a lot easier to find and you can easily build one yourself with simple parts from home. If your amp or pedal is powering on but no sound, then this diy audio circuit probe tool can make the job quick and easy to figure out.

Great video.I made a probe with a pen case and a cap with a copper nail as the probe part. You have prompted me to look at my friends Heathkit receiver with schematic.we shall see.....☺

[@MrNewRevolutionaries]

Very cool dude! Simple but genious.

[@AlYoung]

Thanks man! I appreciate that! It’s definitely easier to use then chasing mA voltages. Once the problem has been detected then the multimeter and transistor tester can do the rest of the deep diving.

I came from the first video nice demonstration i have some polyester and ceramic caps rated at 1KV but with low capacitance 0.001uF and 0.002uF and one polyester capacitor rated at 400V 0.047uF i will try different ones on the probe and see the result

[@AlYoung]

Thanks for watching my videos! I have had good results with the .1 uf cap. So far it’s held up well and protected the tester amp with no problems. Next I would like to build a capacitor discharge probe.

Well done buddy pretty cool tbh man

[@AlYoung]

Thanks Brother!!

[@z80softcard]

Good Idea. Thankyou.

[@AlYoung]

You are most welcome!

[@Truly5Blessed]

Very cool

[@AlYoung]

Thanks Kevin!

[@alphanuevo]

Thanks. I put together a similar probe after watching this video (small headphone amp with spliced RCA cable with the positive lead connected to capacitor and alligator wires for both; used an Android signal generator app also). Anything specific to watch out for when tracing eyelet board pedal builds? I have more parts coming today. The bypass for my build works fine but no signal from any part of the eyelet board. Have a good one.

[@AlYoung]

I don’t think it will hurt anything poking around on a pedal circuit. I would start by probing the input signal. Then follow the signal path until you loose it and possibly take some voltage readings in the area of trouble. Hopefully it will be something simple like a backwards capacitor or crossed wiring.

[@alphanuevo]

@@AlYoung Ok, I'll give that a shot. Thanks!

[@craigheavner8254]

How do you apply it to an amp, not through a pedal?

[@AlYoung]

That is a valid question given the title. I built it to test mainly amp circuits and thought it would be easy to show how it works on a simple pedal circuit. I will make a video showing how to use it on an amp coming up soon.

[@tinkerman9224]

I've built a signal tracer & burned 2 little amps because I believe an impedance mismatch. So I incorporated a transformer to correct the impedance. kzbin.info/www/bejne/g32UXn-EftyqjMU
