The circuit shown is for the left channel only but i want to modify it a bit for a stereo version. Moreover, i want it to be powered by +5v from the laptop usb port. Can anyone help me out?Thank you....This is the original link for the circuit diagram>http://www.learningelectronics.net/circuits/portable-headphone-amplifier-circuit.html Quote Link to comment Share on other sites More sharing options...
