The title of the circuit is a 741 op-amp with output coming out at pin 6 – BUT the pc
layout is designed for a 311 op-amp with the output coming out at pin 7 with NO
connection to pin 6. Either the title should be changed to 311 and the output pin
changed to a 7, – or – the pc layout should be changed to connect to pin 6 and the
marking 311 changed to 741. Make your mind up now! They are different op-amps.
