WebThis extra demand on power supply complexity adds to the cost of class B power amplifiers. Class B. Advantages. Disadvantages. Very low standing bias current. Negligible power consumption without signal. Creates … WebMay 5, 2014 · Which really makes no difference, because it is impossible to eliminate crossover distortion. The main appeal of single ended aplification vs push-pull is that SE distortion is proportional to the input signal amplitude, where PP distortion is inversely proportional to it. In other words, Class B and AB aplifiers distort subtle details first.
