I have recently put an LM386 chip on a breadboard and I have a 1000uF capacitor from the chip output to the speaker. The speaker is very crackly and not a clear pitch. I hooked up an LED and have noticed that if I touch the top of the capacitor then the light gets brighter. I noticed that it does also gets brighter before I even touch the capacitor. I know from reading about the Theremin that the hand has about 2 pF capacitance. Is this capacitor using inductive capacitance to boost it's own capacitance level?
