The AD100VT, AD50VT, AD50VT-212, AD30VT and AD15VT feature our patented VOX Valve Reactor found on all Valvetronix products. The Valve Reactor circuit uses a 12AX7 triode vacuum tube together with an actual
low-wattage tube power amp circuit, a virtual output transformer and a dummy speaker circuit that simulates the impedance changes of a real speaker.
