12BH7

The 12BH7 is a general purpose tube that has gained a reputation among audiophiles for its musical characteristics and versatile ratings. This tube has been widely used in many applications and is often chosen for its reliability and long life.

One of the key features of the 12BH7 is its high transconductance, which makes it well-suited for use in audio amplifiers. This high transconductance allows the tube to deliver ample power and control over the audio signal, resulting in a sound that is both dynamic and detailed.

Another benefit of the 12BH7 is its low microphonics. Microphonics occur when the tube vibrates due to mechanical shock or vibration, producing unwanted noise in the audio output. The 12BH7 is known for being exceptionally resistant to microphonics, making it ideal for use in high-fidelity audio systems.

In terms of technical specifications, the 12BH7 has a maximum plate voltage of 300 volts and a maximum plate current of 58mA. The maximum plate dissipation is 8 watts, which gives it plenty of headroom to handle large audio signals without distortion.

Overall, the 12BH7 is a reliable, high-performance tube that is well-suited for a variety of audio applications. Its musical characteristics and resistance to microphonics make it a popular choice among audiophiles, while its technical specifications ensure that it can handle the demands of even the most demanding audio systems.
