And with good reason, for it was the first time that a design featuring three totally independent, dual channel, all-tube amplifiers was shoehorned into a single device. Tube tone purists were ecstatic. Its state-of-the-art handling and switching logic – optionally controllable via MIDI enabled direct access to six of the most sought- after tonal flavors. And that put at players’ fingertips a sonic spectrum with a breadth unrivalled by any all-tube amp. The TriAmp® MK II was truly a milestone in amp history. Then the engineers at Hughes & Kettner® decided to play matchmaker, marrying the qualities of this milestone to the latest innovations in tube amp technology. They named the progeny of this union TriAmp® MK II. The findings of modern research flowed into the revamped six fundamental sounds. By the same token, the power amp circuit was redesigned from the bottom up, resulting in an even bigger, even more open sound. Next to a variable effects loop (serial/parallel), the TriAmp® MK II was endowed with a Half Power switch. Now you can halve its output power from 100 watts to 50 watts whenever the mood strikes. This lowers the power amp saturation threshold. The flagship of the Hughes & Kettner® Tube Custom Series, the TriAmp® MK II is exclusively handcrafted, bar a few exceptions. Every device is put through the paces of numerous load and safety trials before it is subjected to ultimate test – the ears of experienced guitarists, the most sensitive gauge of them all. When you chose the TriAmp® MK II, you opted for a top-drawer tool built by pros for pros. Courtesy of its versatility, professional-quality features, impeccable workmanship, and, above all, stunning sound quality, it truly merits the moniker “state of the art”, setting standards for generations of tube amps to come.

BEFORE POWERING UP • Check that the local current and the amp's AC power rating are identical before you plug the TriAmp® MK II's mains cord into an AC outlet. • Ensure that air can circulate freely around your amp's ventilation ducts. • Place the amp on a stable platform where it is not exposed to mechanicall shocks and temperature extremes which may damage the amp or endanger the safety of bystanders. • Hughes & Kettner® is not liable for any damage to the amp due to improper use. 1.0 THE THREE AMPS IN THE TRIAMP® MK II Three totally different amps in a single housing? Until the mid-‘90s, this was thought to be an impossible dream. The Hughes & Kettner team was undeterred: Years of intense development efforts and research culminated in the TriAmp®, and this magical combination debuted in 1995. To make the dream reality, we developed an unprecedented switching technology that delivers totally independent fundamental sounds of the highest quality. Each of the three preamps is dual-channel in design so a total of six sounds are available at the touch of a button. How does TriAmp® MK II produce such fundamentally different sounds with just one power amp and a common master section? TriAmp's tonal potential lies primarily in its puristic tube design. Highly advanced new switching technology developed by Hughes & Kettner for this amp reconfigures the multiple tube stages with each new sound you select. This new design pulls every drop of tone out of the all-tube circuitry, lending TriAmp® MK II incredible tonal flexibility without any reliance on solid-state compromises. The power amp design further supports TriAmp® MK II's vast range of tones: In each channel, the Presence attenuation factor is switched automatically via a special capacitor. This lends each channel its trademark power amp characteristics and explains why they are so easily adjusted using just one Presence knob in the MASTER section.
