ONKYO A-8630 hálózati trafó
Jó napot mindenkinek! A típus A-8630. Letakarták és úgy üzemeltették.Kiverte a hálózati biztosítékot.A tulaj átkötötte,és eleinte elindult. Most már csak kiveri a biztosítékot.Ha lekötöm a hálózati trafó szekunder oldalát nem változik semmi.Ha a trafó egyik bemeneti ágát kikötöm nem olvad ki a biztosíték.Szerintem rossz a trafó,de már nem gyártják.Tud-e valaki valamilyen beszerzési forrást? dínó
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.
