Salut! Am un amplificator auto JBL CS60.4 si am o problema cu unul dintre canale, mai exact fata-dreapta... Atunci cand bag mufa rca, ledurile palpaie.... intra intr-un fel de protectie..se aude la inceput distorsionat, insa nu dureaza cateva secunde si se opreste. Vreau sa precisez ca finalii si prefinalii nu au nimic. Insa tranzistorii U1620, intre pinul 1 si 3 imi arata ca sunt in scurt. Parerea mea e ca nu aia sunt o problema deoarece sunt niste  comutatori de alimentare (cred ca asa s-ar zice la switching power supply) :d....Multumesc anticipat, astept ajutorul vostru!
