How to get working UA741CP IC
I don't think that's a dual power supply, I think it's a single power supply with a chassis earth terminal between the two output terminals. 

You need a supply with positive and negative outputs or two supplies that you can connect in series (the minus terminal must not be grounded for that to work). 

You can verify by measuring the voltage from -V to GND and +V to GND with a multimeter.
