The EL34 is a power pentode vacuum tube that was introduced by Mullard in 1955 and is usually found in an amplifier’s final output stage. Befitting its British origins, the EL34 was commonly used in amps built by companies like Marshall and Vox—as such, it became associated with British music of that era.
