Randall Amplifiers takes a different approach to power by developing a completely new proprietary power circuit called Valve-Dynamic, which they feel finally breaks the barriers between tube and FET. Incorporating this tube driven MOSFET power circuit into several of their amps was designed to not only capture a power tube's true reactive qualities including the feel, warmth, and musical character, but combine that with the durability and lifespan of a 400 watt MOSFET power amp. The new Valve-Dynamic power circuit is the lifeblood powering the new V2 and T2 guitar amplifiers.
