Okay guys, I recently posted about this circuit: http://www.allaboutcircuits.com/vol_6/chpt_6/10.html
Come to find thanks to audioguru, the op amp dosn't supply enough current, 5mA.
So basically, can anyone draw me up a circuit of what you would do to replace the op amp? What I have available is little bc547 NPN bjts. Should I keep the op amp and add the little 547s in between the op amp and TIP transistors? What values would be good to use?
I need 100mA supplied to the output stage right? These components names here and general components like caps and resistors is what I already have on tap to use and I would like to stay with what I have.
Thanks..
