Sziasztok!
Ebben a gépezetben a hangerőszabályzó ic száma kellene, mert tök süket a gép, ami szám megmaradt az a következő:9153 vagy OF010A ez maradt meg a ragasztó eltávolítása után mi lehet ez?
| Sziasztok!
A címben említett erősítőben megállt az infra vevő, rajzon ez a tipus szerepel: PNA4823M03S0, a tokon ezek találhatók: H28 U93 07C sajnos ezekről semmit nem találtam sehol. Mivel van itt egy kisebb széria végfok hibával nálam, abból próbára átraktam az infra vevőt és megy tökéletesen, szóval bitos, hogy a vevő a hibás. HQ-nál van ez a nevű: TSOP4838 infra vevő, ezzel ki lehetne váltani? Esetleg ha lenne valakinek bontott infra vevője, az is érdekelne. Üdv.: Viktor |

Sziasztok!
Címben nevezett rádiós erősítő végfok panelján teljesen elégett a VR39-40 0.47ohmos ellenállás.
Miből tudnám ezt újra tekerni?
Vagy helyettesíthető-e a képen láthatóval?
A válaszokat köszönöm!
