12BH7 Tubes

The 12BH7 is a low-gain twin triode, similar in gain to the 12AU7 but able to deliver more current. That makes it a strong driver valve: it's used in the driver stage of amps like the Ampeg SVT, and in hi-fi amplifiers. We stock JJ 12BH7A and Electro-Harmonix 12BH7, including gold pin. See also the 12AU7, or browse all preamp tubes.
