/diy/ - Do It Yourself

ahah, you shouldnt have listened to the anti-LM386 fags. the LM386 input is self-biasing, so you woulnt experienced any of your current problems.

anyway, to fix your shit, you gotta create a virtual ground, and reference all your ''ground'' signals to this instead of the negative of the battery. this automatically biases all your inputs and feedback paths to the half-way supply of your circuit so the signal has room to go both up and down, so you dont get signals with the top or bottom cut off, but sinewy beautiful full sine waves.

pic related is a good way to do it. use 10K for resistors. you can also eliminate the op-amp, and just use the centerpoint, but that's not as good. google ''virtual ground driver'' for info if you wanna read about it.
