ONKYO amplifier dolby surround, Problem with a Switching Diode
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.

Nordmende V 31 rádió végfokhibás
Sziasztok!
 Ez a készülék nem HI-FI, de rádió, és legalább 40 éves.
 A készülék egy táskarádió, ami majdnem teljesen "süket". Mint kiderítettem, végfokhibás. A tanyán, ami található, az egy IC-s végfokkal rendelkező készülék rajza, de sajnoz a fenti GE-tranzisztorokkal, trafókkal (fázisfordító, és kimenő) szerelt, szerintem korábbi változat. A hiba a ff trafó környékén lehet, ahol megszakadt egy R148 jelzésű ellenállás. Színei kopottak, talán fehér, szürke,narancs, vagy piros, és arany. Egy 10kohm-ot tettem be próbára, fel is hangosodott, de torz. Változtatva az értékét sem lett jobb. Még más gondja is van, tehát jó volna egy rajz a végfokról. Ha valaki tudna segíteni ebben, a tulaj (is) örülne a patinás, öreg, működő gépnek.
A belső cimkéjén a felirat:

Köszönöm a segítséget.
Üdvözlettel:
Attila
