12 AU7-EH double triode tube

Ideal for high-quality Hi-Fi audio applications, but also for music (guitar and bass amps, etc.).

The Electro Harmonix 12AU7 offers low microphony and high linearity. It is the equivalent of the ECC82, but a reproduction of the famous NOS GE 6189 model.

Electro-Harmonix tubes are all new designs and of excellent quality. Many manufacturers use rebranded Electro-Harmonix tubes in their amplifiers. If you're looking for high-quality tubes at a very reasonable price, Electro-Harmonix tubes are for you.
