Ray Tubes KT88 Select vacuum tube

The KT88 is a beam tetrode introduced in 1956 as a variant of its smaller cousin, the KT66. Its name is derived from kinkless tetrode, an earlier name for the beam tetrode, and itʼs been popular in high-fidelity stereo systems since its introduction. Since New Old Stock of the KT88 is especially rare, Ray Tubes is proud to offer brand-new KT88 vacuum tubes.
