How to amplify signal to transistor. Answered
I have created a circuit using the diagram found here:
The only differences in my circuit are that I only have used one LED and one 3 volt coin battery. I want to install this circuit in my headphones with the L/R and Ground soldered to the terminals of the speakers. On testing the circuit, I found that the light is only clearly illuminated when the volume is set to max, otherwise, it is very faint. I want it to work at lower volumes. How do I amplify the signal going to this circuit without building a headphone amp? I only want to amplify the signal going to this circuit, not the headphones. Thanks in advance.
