Brand New In Box Gain Matched Quad (4) Tung-Sol Reissue KT120 / KT-120 Vacuum Tubes The KT120 is an incredible tube. Essentially a KT88 / 6550 on steroids, they are capable of pushing 150 watts per pair of clean power in a push-pull configuration. Because of the high wattage these have become a favorite among bass plays and guitarists who want the ultimate in clean headroom and volume.
