Overall:

Gianni 15/02/2018

Ottimo amplificatore basato sul famoso TDA2030. La qualità di questo integrato, da decenni utilizzato in audio consumer è eccellente. Il costo dell'amplificatore montato è irrisorio. Un piccolo ripple dovuto allo scarso filtraggio dela tensione di alimentazione, ma si può rimediare aggiungendo un condensatore sull'alimentazione. Un po' piccoli e vicini i contatti di alimentazione e ingresso. Per il resto ottimo. C'è pure un trimmer per variare la sensibilità in ingresso.
