Ruby Amp Speaker Output jack

[bzblues]

Hello everyone!

I've built a Ruby amp, the amp works fine and sounds very cool! the thing is that I wanted to add a speaker output jack to the circuit but it didn't work. I plug it to a 6 ohm speaker and also to a Roland Street Cube amp but no sound came out of them. Is the wiring OK? I'll attach the picture.

Disclaimer: I'm very new in electronics so my knowledge is little.



Thank you!

The jack as wired in the drawing should work. Make sure you indeed have it wired exactly as the drawing. For example if you got left and right mixed up it won't work.

The input jack is backwards. The front panel side is on the left. The tip/sleeve labels are correct

Here is a corrected drawing and a suggestion. The input jack is connected directly to the gate of the FET. A resistor and capacitor would help protect the FET from static charge or DC on the input.
