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

Hoy tropecé con esta reliquia y tenia el diagrama

A fenti erősitő előzménye, hogy a kimenetét 4db hangfallal jól leterhelték.
Ezt követően a hangerő poti kb. 1/5 álásánál elkezd torzitani és erőtlenné vállik minha nem kapna tápot.
A tápfeszültségek mindenhol rendben vannak. A torzitás kezdetekor a végfok IC lábán 2volt feszültségesés volt mérhető.
A végfok elótti nagyjelü meghajtónál is ez a torz hang van jelen.
Ha volt már ilyennel dolgotok vagy tapasztalat ötlet, kérném osszátok meg velem.
Köszönettel: Kitimi51
üdv: most raktam be egy ilyen erősítőt a barátom motoros sisakjába, 2 db fejhallgató hangszóróhoz.
