Randamentul tipic al unui amplificator clasa AB este in medie 65-75%, la o schema total simetrica, de la intrare pina la iesire.

 

Mai jos de atit , ca randament cobori AUTOMAT,cind ai componente de proasta calitate, o schema prost conceputa, si asa mai departe.

 

Deci in idee atingi MAXIM 75%, cu o schema "la superlativ".
