Yes - do not use this circuit. It will not work as intended for several reasons. Even if a 741 had enough output voltage swing and output current capability to drive the LEDs, the LEDs will not come on sequentially like a bar graph. The output circuit is all wrong, indicating that whoever posted this circuit never built it. LEDs and resistors do not function the way this circuit intends. If you want a bar graph display, better to start with something based on the LM3914 or 3915.
