    Phi 170 The VAC iQ is the only system able to hold each output tube’s true underlying idle current perfectly steady at all times, no matter how much you turn up the volume. Say goodbye to manual tweaking, bias drift, thermal tracking effects, dynamic load-line shift, runaway tubes, and blown fuses. Say hello to more detail, increased extension and punch, lower noise, less distortion, and high reliability. It will even tell you when it's time to replace weak tubes. The Phi 170 with iQ System. Superior sound. Only from VAC.
