Symptoms of Bad Capacitors
An electrolytic capacitor can fail gradually over a period of years as it dries out. The insulator in the capacitor becomes inconsistent, and its electronic characteristics drift. In audio amplifiers and related equipment, this causes problems with the dynamic range of the sound. You hear crackles in the music and it will sound weak.
