VACamps

The VAC iQ Intelligent Continuous Automatic Bias System The VAC iQ system of intelligent continuous automatic bias(patent pending) is the result of 18 years of research and development by the engineers at VAC, and represents the first time in history that each tube in the output stage of a vacuum tube amplifier can be held at the optimal bias point (quiescent current) at all times, regardless of how loudly or softly the music is playing. The result is sound that is always the best it can be, reduced distortion and noise, and elimination of tube failure drama, all without any effort by the user. The VAC iQ Intelligent Continuous Automatic Bias System is, to put it mildly, a very big deal.
