Lots of kinds of diodes are used in amplifiers. In the power supply section, diodes may be used in groups of two or four, as rectifiers to convert AC (from the mains supply, via a transformer) into DC for the amplifier. These diodes are usually rated at several hundred volts, and several amps. They are classified as rectifier diodes.
