Ray Tubes SELECT KT88

SELECT KT88

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 it's 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.

Sounds Characteristics 

The SELECT KT88 excels at powerful bass and high-resolution sound, built for the low-frequency demands of rock and symphonic orchestras.

• The bass is solid with a powerful deep end, suitable for highly dynamic music like rock and symphonic orchestras.
• The midrange frequencies are delicate and multi-layered with a warm tone. Vocals and strings in particular excel.
• The treble performance is clear with very high resolution and rich but not harsh details.
• The dynamic range is very wide, while the soundstage is wide and deep with extremely accurate positioning.
