" Clasa " depinde de modul de polarizare al tranzitoarelor finale. 

Concret, de R377, R378 si R3870. 

 

R382 si termistorul R383 regleaza simetria finalilor. .........la care se adauga R384, reactie negativa in cc + ca

 

.........
Prea multe variabile care trebuie stabilite corect.........si de aici amplificatoarele noastre nu prea merg cum zice in carte ca ar merge.
