Mercury’s Patented Amp-Saver technology actively senses the power (voltage and current) being drawn by your amp at ramp up and ensures your amp doesn’t inhale anything harmful. Seamlessly working with your amp’s on/off switch, using the AmpSaver translates to longer tube life, less heat, and avoiding costly repair bills. Fused for 5A, the AS-1 can benefit tube amps from 5 to 200 watts.
