Normende stereo 6020St

Recommended Posts

Va salut,

de curand am intrat in posesia unui amplituner normende, destul de frumos si de vechi ca sa merite o reparare.Problema care este - un canal este mort complet. Un tranzistor se incalzeste intr-una , cel incercuit.

Nu am apucat inca sa fac nici o masuratoare deoarece sunt plecat. Dar, in caz de deces al tranzistorului final, cu ce as putea inlocui perechea mje105/205? Eu am Tip31B/32B, dar nu cred ca sunt suficient de puternici.

Mje: http://alltransistors.com/transistor.ph ... stor=40708

Tip31: http://alltransistors.com/pdfview.php?d ... =_motorola

Puterea amplitunerului este de 2 x 15W/4 ohm.Vor face fata?

Daca nu, ce tranzistori recomandati?

Va multumesc.

Se poar pune perechea BD911/912 sau capsula mai mare TIP35/36,BD249/250.Numai sa verifici curentul de mers in gol, sa nu ai tensiune pe iesire.

Problema este ca terminalele sunt inversate la mje-uri, respectiv baza cu emitorul, fata de bd-uri.M-ar fi interesat o pereche pe care as fi putut sa o montez direct, fara improvizatii.
