Filter capacitors in an amp''s power supply smooth out pulsating DC (direct current) coming from the amp''s AC rectifier (the device that lets current flow just one way). Filter capacitors store electric charge as it flows in from the alternating house current (the AC).
How much goes where is determined by the instantaneous voltage coming from the rectifier, the instantaneous voltage on the capacitor, and the current requirement of the load. As shown in the right-side drawing, the output voltage (the voltage on the capacitor) increases whenever it is less than the input waveform.
