An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of

…virtue of their topology. Instead, DC voltage in the output section is blocked by an output coupling capacitor - typically a large-value (3000-6000μF) electrolytic capacitor - which is interposed between the amplifier's output section and the loudspeaker. There are several practical approaches to the design of an OTL…
