Class-A Output Stage & Active-Servo Bias Vacuum tube power amps with class-A outputs are rare. Class-A operation causes the tubes to run quite hot, and increases the chance of saturating the output transformer. Margules has gotten around this problem by incorporating Active Servo Bias (patent pending). The bias actively tracks in input signal, permitting full class-A output, without overdriving the tubes. Active Servo Bias also sets DC bias and AC drive levels, assuring optimum electrical and sonic performance. Throughout the useful life of the output tubes, no drive or bias adjustments are ever needed. New tubes can be installed without test equipment or a time-consuming setup. Active Servo Bias also makes it possible to use a variety of output tubes. The 6550, KT88, KT99, or KT100 can be interchanged without modification. Active Servo Bias is implemented with semiconductors designed for the aerospace industry, assuring long, trouble-free operation. Ultralinear/Triode & Strapped Operation Audiophiles have
