Sziasztok!
Behoztak hozzám egy AET 453-at ami hangszóró oldalról villámból adódó túlfeszt kapott.
Halott volt a 2 db végtranzisztor, BC301 és BC 303 is. Természetesen meghalt BC212 és 182 párosítás is a lábaikon lévő 1n4148-akkal együtt.
Ami eddig cserélve lett:
A 2db 2N3055, BC303, 301, T7 BC182, T6 BC212, D4,D5,D6,D7, T2, T3, C6,
Szakadt vagy nyúlott ellenállást nem találtam.
A tápágakba kötött 10 ohmos ellenállásokkal indítottam, és tápáganként 2,1 Ampert vesz fel a szerkezet!
Kint van az egyen a kimeneten.
Nem értem min a törpöm lehet vele!
Valakinek esetleg valami ötlete?
Szép napot mindenkinek ! Térképet keresek ehhez az aktív ládához.
Bowers&Wilkins ASW 675 Előre is köszönöm !
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.
