The first electronic amplification of sound was done with Vacuum Tubes. We have pre-amp, power and rectifier vacuum tubes among other types in New Old Stock from the golden era of American & European manufacturing as well as current production tubes from today.
Vacuum Tube - EL34 II, JJ Electronics, Pentode
A different construction of the classic EL34 tube that offers a different tonal palette than the original. This tube has a more compact plate structure than standard EL34’s. The JJ EL34 II has an increased low to low-mid end with plenty of headroom to spare. The JJ EL34 II is stronger than the original but not harsh sounding in any way.
