Sziasztok!
A fenti erősítő kapcsolási rajzát keresem, aki tud segítsen.
Előre is köszönöm. További szép napot mindenkinek.

Sziasztok!
Van egy "D" osztályos hifonics autós erősítőm. Fet-eket kellett benne cserélnem, mert elszálltak. Gyárilag SW50N06 volt benne, viszont ilyen nem kapni itthon sehol sem. Helyette FQP50N06-ra cseréltem mindegyiket. Most elindul az erősítő, de ahogy jelet kap, kicsapja egyből mindkét biztosítékot.
Mi lehet a probléma? Ennyire fontos lenne, hogy ugyan olyan FET-et tegyek bele, mint ami gyárilag benne volt?
Előre is köszönöm a segítséget!
Hello, I got a problem with my Sony Receiver STR-DE 225.
There´s a sudden interruption of Audio in non defined intervalls - may be once ore 6 times during appr. 5hrs operation.
Interruption does not depend on Volume. Connection cables and speakers I´ve checked.
There´s a loud crack in both speakers, display shows for short time "PROTECTION".
After switching off and on again, everything operates normal until next interruption.
I removed from the inside of the receiver a lot of dust with a vacuum cleaner, but this didn´t help.
Unfortunately Sony has no documents for this device, as it is To "old" (1996), or could give me a hint,
in what cases "PROTECTION" might appear.
Is there anyone to give me a clue? Thanks
