What is a single-ended amplifier?

A single-ended triode (SET) is a vacuum tube electronic amplifier that uses a single triode to produce an output, in contrast to a push-pull amplifier which uses a pair of devices with antiphase inputs to generate an output with the wanted signals added and the distortion components subtracted.

What does single-ended input mean?

A single ended input measures the voltage difference between a wire and the ground. This difference is then amplified to provide the output. Single ended inputs can suffer from noise as the wire that carries the signal picks up electrical background noise.
