duál fet pótlás
Segítségeteket szeretném kérni. Van egy SANSUI erősítő aminek a végfok bemenetén egy duál fet csücsül UPA68H. Javítani próbálták gépet és ezt kicserélték egy K129A típusra, gondolom mert az eredeti nem beszerezhető. Sajnos ez a pótlás nem lett jó mert torz jel jön ki a fetekből. Mit tanácsoltok mivel pótolható az eredeti. Köszönettel Laci
EF806S elektroncső
Sziasztok! Otthon, keresgélés közben ráakadtam 4-5db Tesla gyártmányú EF806S jelű csőre. Ránézésre elég újnak tűnnek. Kis google keresgélés után kiderült, hogy népszerű csövek a hifi technikában, de konkrét kapcsolási rajzot nem sokat találtam. Foglalkozott már valaki ilyennel, vagy van valakinek tapasztalata ezzel a csővel?
KRK VXT4 studio monitor speaker - mains hum. Schematics required
Hi - I have a pair of KRK VXT4 studio monitor speakers. Very expensive! When I stored them, they were working fine. When I tried to use a few days ago, one of them simply hums loudly at 50Hz. I have tried replacing the two 12000uF PSU capacitors, as I found on Google that sometimes they can become depolarised but this has not solved the problem. I am trying to find a schematic for both the main board (which has the PSU and the PA stage) and the pre-amp board. - Thanks, Kevin
Panasonic SA-HT520 nincs hang
Sziasztok! Van egy Panasonic SA-HT520 Home Theater szólt egy darabig azután kattant egyet és azóta tök süket. A vezérlő egysége nem ír ki semmilyen hibakódot, látszólag jó csak az Active Subwoofer nem szólal meg. Lehet végfok IC?
