Hi all,
I'm trying to build a simple headphone amplifier with op amps and i want to add a bass boost feature controlled by a potentiometer. My goal is to try and make it with just one op amp, maybe a passive bass boost at the input and the op amp to act like an amplifier at the output.
I tried a few circuits but i don't get good results and i get oscillations with some of them. I found one more promising circuit but i'm not sure how to make it a bit more simpler (without the fets and and the buffer) : https://tangentsoft.net/audio/ppa/amp2/misc/schematic8.pdf
Any suggestions will be appreciated!
