audioguru said:Supply bypass capacitors are connected from +12V to 0V and from -12V to 0V. They keep the power supply voltages from bouncing up and down with the signal, if the supplies are disposable batteries or other voltage sources with internal resistance.
yes the circuit has a 330uF capacitor between power supply pins,
i'll try to make the circuit on a PCB rather than a breadboard, so perhaps i could solve the problem with this job.
thanks alot for all helps and apologize for all bothers about my broken english language.
