Vad multe amplificatoare la 100 W si peste si as dori sa pun o intrebare : ce boxe ar trebui si cat ar costa ( pentru cele de 100 W ) ?

Eu va prezint o schema mai modesta, dar compenseaza prin documentatia bogata, este vorba de Aleph 3.

1. Un exemplu practic de executie a unui amplificator simplu pe MOSFET si TEC-J de 2x 100W in clasa AB (special pentru cei mai pretentiosi audiofili):

In primul rand vreau sa salut Comunitatea Tehnium fiind nou venit.

Vreau sa prezint o schema de amplificator Hi-Fi cu tranzistoare 2N3055 si alimentare asimetrica.

Schema a fost preluata de la Dn. Nicusor din Craiova.Pentru mai multe scheme vizitati www.tehnic.go.ro

Schema a fost preluata dintr-un Almanah al Revistei Tehnium din '80.Amplificatorul are o putere de 100 W.
