Am desfacut aparatul si am identificat un transistor topit 20N60A4D iar altul lipsa(taiat) si inca un condensator lipsa,taiat am incercuit in poza. Aparatul cred ca a fost desfacut si reparat sau incercat sa fie reparat se vede ca este dat cu ceva vopsea albastra. Mentionez ca l-am primit de la cineva in rest nu stiu nimic despre aparat. Unde as putea gasi un astfel de transistor? sau ceva inlocuitor.Multumesc
