Levehető előlapos autórádiók csatlakozói.(Molex)
Sziasztok! Valaki tudja esetleg hogy hogy a gránátba hívják azokat a csatlakozókat amiket a levehető előlapos autórádiókban használnak az előlapnál? Egy olyan csatlakozó kellene nekem 2x10 érintkezős párban de nem tudom milyen néven keressem. Válaszokat köszi Tibor A tipus kiderült most ilyet keresek akár bontva is. Vagy alternatív megoldást a kiváltására.
Rotel RA-980BX equivalent transistors
Hi All,


I have a Rotel RA-980BX amp with a blown channel. I have sourced most of the transistors, but am struggling to find the other 4.


Part numbers as follow:
2SC3478
2SC4381
2SA1376
2SA1667


What would be suggested equivalents / suitable replacements?


Also, some advice, I suspect the bias pot to be bad. Based on the circuit, would you think that the bad bias pot would cause the drivers and outputs to blow? Any suggestion on modification to prevent this re-occurring?


Thanks



Regards,
Werner
