Salutare.Am un amplif Pioneer VSX-D514 cu defect.Dupa indelungi stresuri cu masuratori si verificari, am descoperit cum ca daca il resetezi, afiseaza el problema, in cazul meu fiind "AMP ERROR". Am descoperit pe 2 canale curent continuu, deci, tranzistor final ars. (Ciudat ca are 2 integrate, unul pentru Front LEFT si Center si celalalt pt. celelalte 3, in fine)Am decuplat alimentarea acelui integrat si ampliful merge bine merci, fara probleme (ma lipsesc de cateva functii de reglaj, neavand FRONT).Integratul final cu defect este Pioneer PAC010A - hybridAm gasit pe net asa ceva, dar e vreo 150 Ron, Am gasit totodata si un echivalent, respectiv STK-411/230EIntrebarea mea e, daca iau inlocuitor, se va simti vreo diferenta sesizabila asupra calitatii sunetului?Mi-e oarecum si frica sa iau original si sa se arda din cauza unei piese minuscule din etajul prefinal.....sau mai stiu eu ce.....Astept pareri, ce imi recomandati.??Merci
