Sunt diode zener pentru alimentarea TL071, care are functia de sumator activ in acest montaj, nu stiu ce valoare au, dar sigur nu peste tensiunea maxima admisa de acesta(TL071), +/- 18V.

Rog pe dl Robert22 sa posteze daca are si se poate si lista cu componente pt a ma lamuri cu acele diode zener, as vrea sa il fac (amplificatorul) asa cum trebuie sau mai bn zis "ca la carte".

difuzorul pe care il am (SAL BXC2020). "Pm /Pn : 80/50 W f: 50 - 5.000 Hz SPL1 w/1 m: 89 dB

 

Problema este difuzorul, nu amplificatorul. Cu acest SPL teoretic de 89db, daca vei aplica 50W acestui difuzor, se va auzi la fel de tare ca si cum ai aplica aproape 7W unui difuzor de calitate ridicata cu SPL=98db.

Ati reusit pana la urma sa realizati amplificatorul. Rezultatele sunt cele asteptate?

Il descarci de aici. Il dezarhivezi unde vrei sa-l folosesti si este direct functional. Merge si pe stick.

Scuze pt off-topic!
