I need a split rail circuit for a 741 op amp.
The circuit can be found here:
or here (the latter can be simulated).
I have simulated the circuit in three different programs an it always seems 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. A photo of the breadboard circuit is here:
The circuit is damn simple, it puzzles me why it doesn't work. Again, I checked polarities, power, etc. Any help would be appreciated!
