These extremely rare 2A3 lamps are in excellent condition, with preserved original boxes. Slight traces of age and patina only confirm their authenticity. During the period of production of these lamps, RCA set industry standards in terms of quality and innovation, so it is rightly considered that they originate from the golden age of audio technology.
When installed in a Single-Ended Triode (SET) amplifier, these 2A3 tubes deliver a warm, rich sound and exceptional musicality. They stand out for their natural vocal reproduction, pronounced mid tones and impressive soundstage depth. Thanks to the linear operation in class A, they provide the famous "triode magic" that easily conquers and raises the listening quality to a completely new level.
