salutare...vreau sa creez o clona la acest amplificator si am nevoie de putin ajutor.....amplificatorul o sa-l alimentez la 30Vcc, o sa-i adaug alt vu-metru si o protectie.....ce vreau de la voi este sa-mi spuneti ce piese trebuie modificate pentru tensiunea aia (rezistente, diode, tranzistori, etc) si ce imbunatatiri i-as putea aduce?....(PS: am citit toate topicurile despre acest amplif).va multumesc

La etajul final, inlocuieste driverul si generatorul sau de curent constant cu niste tranzistori mai robusti decit BC-urile alea ! Tranzistorul din superdioda il poti inlocui cu ceva in capsula TO126 ca sa il prinzi mai usor. Deasemenea R152 si R252 le vei inlocui cu 1K5 / 1W.
