Output transformerless

ID: output-transformerless

Output transformerless (OTL) refers to a type of amplifier circuit design, primarily used in audio applications, that operates without an output transformer. In traditional amplifiers, output transformers are often used to couple the amplifier's output stage to the loudspeakers, particularly when dealing with vacuum tube amplifiers. However, OTL designs eliminate the transformer, providing a direct connection to the speakers.
