I got stuck on this circuit and I need to find a solution...and even I reduce the gain by use smaller values for resistors still facing some troubles above 2 KHz .
Does any Know how to design simple Stereo Audio Amplifier(Pre-Amp+Tone Control+Output Stage) by using LM358 op-amp and (8 ohm Speaker) ,the circuit should be working with 4.5V (e.g. 3 AA batteries)..?
I designed several circuits but I got 2 much noise
