Am un pre-u ars de fiul meu care a bagat pe intrarea de DVD iesirea de casti de la un MP3 stick.Probabil a bagat nivel prea mare ca a trosnit pre-ul cu numele NJM2068.Un amplif operational in carcasa online cu 7 pini.pinout:1 - A output2 - A- input3 - A+input4 - V-5 - B+input6 - B-input7 - B output8 - V+(12 Vcc)Exista 3 variante1 - spuneti voi unde-l gasesc2 - tot voi spuneti ce s-ar potrivi in locul lui fara modificari pe cablaj3 - faca rocada cu cel de pe intrarea phono,care si asa nu prea se mai foloseste in ziua de azi. cu multumiri anticipateNicu

NJM2068 este echivalent cu MC33078. Cred ca la DVD pe intrare ai varianta acestui circuit integrat in capsula SIP8 sau SSOP8, o sa poti utiliza aceeasi varianta de capsula si pentru MC33078.Succes la schimbat circuitul integrat si...NUMAI BINE
