I need virtual ground for a 741 op amp. The circuit schematics are here, the later can be simulated:http://tangentsoft.net/elec/bitmaps/vgrounds/rdiv.pnghttps://www.circuitlab.com/circuit/y9x79d/rail-splitter/
I have simulated the circuit in three different programs an it always seem to work. However, when I build the circuit on the breadboard, it doesn't work. With 9V DC supply instead of getting 4.5V, 0V and -4.5V I get 9V, 4.5V and 0V. It seems as if the caps weren't even in the circuit. I checked the polarity and the value of the caps and even used different ones. Still don't get any virtual ground, the circuit acts as a voltage divider.

The circuit is damn simple, it puzzles me why it doesn't work. Again, I checked polarities, power, etc. Any help would be appreciated!
