VK-56SE uses a 6C33C-B triode output tube that offers many times the current delivery of the 6550/KT90 tube variant used in most traditional tube amplifiers. VK-56SE also incorporates vacuum tube current sources for the first gain stage to provide an unforgettably soulful portrayal of harmonic texture and instrumental timbre. Your recordings will sound more alive while simultaneously yielding greater finesse, grace, and inner detail.
