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 :-)

Sziasztok!
Ebbe az erôsítôbe elment az STK463 2x25W Unom ±26V Umax±38V, mivel mostmár nem 220V van ezért a maximumon ±37.5V on van hajtva az STK.
Nekem van STK460-om ezt szeretném betenni Unom±23V Umax±32V 2x20W.
Le kellene vennem kb ±10V-ot, mivel birnam ezt olcsón megoldanom ?
(7824/7924 nem jó erre mert rövidzárvédettek. Trafónak csak egy primerje van, szekundert nem lehet letekerni).

Üdv Mindenki!
Van egy (ráadásul) saját végfokom.
Bekapcsoláskor kiül pozitív dupla tápfeszre (mivel H osztályú) utána beáll 0V a kimenet, de ez idő alatt a védelem megfogja és megáll. Az összes FET (IRF) illetve tranzisztor (MJ) jó benne.
Ha kiveszem a kapcsoló FET-eket akkor is megcsinálja ugyan ezt (!).
Ha a védelmet leakasztom indításra, majd vissza akkor utána tökéletesen "muzsikál".
Valakinek valami tipp?
A rajz itt is fent van.
üdv.
Mihi
