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 :-)

Szervusztok!
Van egy STR DE 875-ös erősítő nálam aminek kitörték az antennabemenetét - sajnos - 4 SMD alkatrésszel együtt. Rengeteg rajzot találtam hozzá, de a tunert egyik sem részletezi, csak egy blokséma van mindegyikben. A part. száma 1-693-539-21 vagy ...540-21. Ha valaki tudna közelebbit erről megköszönném nagyon.
Sziasztok!
A címben említett erősítő tápja azt produkálja, hogy a STB 5V pulzál rajta, ha a front panel csatlakoztatva van, akkor a power led jól mutatja a jelenséget. Nem védelmi módban van, hanem tényleg mérve is, mászkál a táp folyamatosan 2-5V közt. Elkók esr-re, kapacitásra jók. TF91 trafó és az IC91 névre hallgató pwm contorller is jó. Aki esetleg javította ezt a kapcsolóüzemű tápot, adhatna pár tanácsot, mert ezekben nem nagyon vagyok otthon...
Köszönöm!
Üdv.: Viktor
A hibát az IC92 pwm kontroller okozta, de jól meg is szívatott mert rendeltem a HQ-tól, még szerencse, hogy 2 db-ot, persze amit elsőre beforrasztottam halott volt, és el vitte magával az IC91-et is. Mindkettő cseréje után a táp elindult.
