Rotel RT 950bx tuner javítása
A címsorban nevezett tuner javításához keresek segítséget. A nagyfrekvenciás dolgokhoz nem értek. A hiba az, nem érez a rádió térerőt, ennél fogva nem szól, sem semmi térerő kijelzése nincs. A hiba helyét már megtaláltam. A bemeneti egységnél lévő varikap lábára rámelegítve többször életre kelt már. Most megint előjött a hiba. Újra kellene hangolni, meg minden a tunert, mert szerintem amikor ment, akkor sem max. térerővel ment. SOS Üdv

Rotel RSX-1055 távirányítóra nem reagál
Sziasztok!
Hozzájutottam hibásan ehhez a gépezethez, sikerült is életre kelteni, de van egy apró "hibajelensége".
Az erősítő tökéletesen működik, viszont ha kikapcsolom a távirányítóval (standby-ba), kb fél óra után már nem lehet bekapcsolni a távirányítóval, csak ha az előlapon ki-be kapcsolom a főkapcsolóval.De ezek után a távirányítóval ismét minden működik.
Találkozott már valaki ilyen jelenséggel?
 
Rotel RA-980BX equivalent transistors
Hi All,


I have a Rotel RA-980BX amp with a blown channel. I have sourced most of the transistors, but am struggling to find the other 4.


Part numbers as follow:
2SC3478
2SC4381
2SA1376
2SA1667


What would be suggested equivalents / suitable replacements?


Also, some advice, I suspect the bias pot to be bad. Based on the circuit, would you think that the bad bias pot would cause the drivers and outputs to blow? Any suggestion on modification to prevent this re-occurring?


Thanks



Regards,
Werner
