electronistu89 Posted November 18, 2022 Share Posted November 18, 2022 Buna ziua, am la reparat un amplificator cu tranzistori 2N3055 cu unul din canale defect , mai exact finali arsi , rezistente arse si BFR39 si BFR79 arsi. Am gasit restul componentelor dar nu pot gasi acesti tranzistori! Stie cineva cu ce i-as putea inlocui sau unde pot gasi originali la noi in tara? Multumesc!

adydep Posted November 18, 2022 Share Posted November 18, 2022 Un amplificator modest cu 3055... cred că merge și perechea A1013 cu C2383,sau chiar 5551 cu 5401. Quote Link to comment Share on other sites More sharing options...
