The maximum efficiency of a class A amplifier, which is likely the type of amplifier being described given the context, is 25%. This is a theoretical maximum, assuming ideal conditions, and is calculated based on the fact that in a class A amplifier, the output current flows for the entire cycle of the input signal.
