Sziasztok!
Van egy Sanyo C4 rádió, amit anno áthangoltak keleti normára, most vissza kellene hangolni. Sajnos műszerezettség hiányában nekem nem megy, a tulajnak meg (jogosan) szívügye a rádió.
Tudna valaki segíteni?
Üdv: Jácint
Üdv Mindenkinek!
Segítségre lenne szükségem.
Technics SE HD50 mini hifihez keresek összekötő szalagkábeleket.
Honnan lehet beszerezni?
Köszönöm!

Hello,
Sony TA-F317R erősítőben a végfok tranzisztorok és a meghajtó IC megadták magukat. IC szállítás alatt, viszont tranzisztorokat elfogadható áron nem tudtam beszerezni, így a helyettesítés maradt.
Eredetileg 2SC3853 (NPN) és 2SA1489 (PNP) komplementer párok vannak benne. Itthon a 2SC2581 és 2SA1106 párost találtam, ami nagyobb áramot bír és elég hasonlóak a paramétereik és szintén komplementer párok.
A neten BD245 és 246 helyettesítést ajánlanak, de ezek paraméterei eléggé eltérnek az eredetitől.
Kérdésem, a fenti 2SC2581 és 2SA1106 páros megfelelne-e v. simán használjak BD 245-246-ot, nem okozna gondot és nem kell a munkaponton állítani? Szükséges-e a másik (jó) végfokban is cserélni a tranzisztorokat (hogy szimmetrikus maradjon)?
Köszönöm.
Üdv

Hi all,
I need a little help to repair my Akai PM-750 amplifier (part of system mx-750).
The voltage selector has broken and I don't know wich wires shoud I put together to get it work under 240V.
Service manual is no help, they just give spares parts...
Huge thanks to who could help me :-)
