About the amp
The KT66 is a very important valve in the evolution of the Marshall amp. It was originally manufactured by the Marconi-Osram Valve company as a British alternative to RCA’s 6L6 power valve. Just like the 6L6, the KT66 is a beam tetrode but with an improved design that eliminates the renowned kink in the 6L6’s voltage/current curve. That’s where the initials KT come from – Kinkless Tetrode.
Back in the day the KT66 was the Rolls Royce of audio valves, and was standard equipment for many classic valve hi-ﬁ designs. It is also capable of handling much higher voltages and currents than a 6L6.
The sound is not quite as aggressive as a standard EL34, but it is punchier than a 6L6, with tighter bass response and improved mid-range clarity.
“I wanted the Vintage Modern to nail those classic tones of the JTM45 and pre-EL34 heads,” says Steve Dawson, Marshall’s design engineer. “KT66s were the only way to go. If you want to get that classic Bluesbreakers tone, it’s there – so is the tone Ritchie Blackmore had on the early Deep Purple albums. This is an amp that’s designed to respond to the guitar like old amps did, so there’s a lot of dynamic range and players who know how to vary their sound from the guitar’s volume control will get the most from it. ”
