Triode-pentode used in low power hi-fi amplifiers.

2 tubes, matched as pair

EL34 II has fuller low mids and low end but does not lose headroom in the high end. Stronger than regular JJ EL34 but not as aggressive as the JJ E34L.

Universal size for 12" speakers
Dome diameter: 80 mm - recommended for most of the guitar loudspeaker with average beaming

As the frequency increases, the radiation of a loudspeaker is increasingly focused on its center. If the listener is in this beam, the sound is extremely harsh and biting; if one moves to the side of it, the sound becomes significantly darker and treble components are partially missing.
To reduce this behavior, a diffuser is used. This sits directly in the beam of the speaker and deflects the high frequencies very strongly, it breaks the "beam". This makes the sound much fuller and more balanced.

Super-Premium Gold Pins Twin Triode with superb linearity, balanced sections, and extremely low noise. The reissue Genalex Gold Lion ECC82/B749 has been carefully engineered to recreate all of the attributes of the ultra- rare NOS original. With balanced triode sections.
