Sziasztok!
Abban kérném a segítségeteket, hogy egy Onkyo A830-as erősítőnek kellene a rajza. Pontosabban elég volna csak a végfokról. Föltettem az SM-keresőbe, de pont olyan nincs. A hasonlóak mind IC-s kivitelűek, ez pedig tranzisztoros, mégpedig jó sok tranz-al van felépítve Jó volna, ha valakinek volna a végforól rajza, mert a többi ákör, és a másik végfok működik.
Köszönettel:
Attila

Hi everyone
Could somebody tell me if I can replace a switching diode to another one, the one installed in the onkyo is a 1SS252 and is 10 times more expensive that a 1SS355.
Usually I order the same but they are pricey (around 10.00 usd for a 100) and not commonly used, not many sellers.
For the 1ss355 every seller on line has it in stock and it's around 1 to 2 usd for a 100.
Ans they are available locally, not in china waiting 5 weeks for the part.
Thank you.
