STK4151-es ic helyettesítésére keresnék megoldást,esetleg ic-t.
Üdv
Szükségem lenne egy 300W-os erősítőre aminek 18KHZ-22KHz tartományban kellene működnie. Tud valaki ilyet hol lehet kapni, esetleg kapcsolási rajz az építéséhez?

Sziasztok!
A fenti arm végfok csere után működik (zárlatos volt) de némítja a bal csatornát. Szinte azonos a Panasonic Audi Concert CQ-LA1923L típussal. A rajz itt található:
http://elektrotanya.com/?q=showresult&megnev=&megnev2=AUDI_CONCERT_CQ-LA1923L&kategoria=&kat2=schematics
Az IC204 (a rajzon a jobb felső sarokban) egyik bemenetén (6-os láb) mérhető a bal csatorna jele, de a kimeneten (1-es láb) nincs semmi. Az IC a másik bemenetre kapcsol, mert a bemenetválasztó lábán 0V van. Ez jogos is, mert a proci, IC604 5V-ot ad ki a 40-es, C jelzésű lábán.
A kérdésem az, hogy miért? Ez így normális? Lehet, hogy beszerelve a csati valamelyik lábán kap egy olyan jelet, amelyik megszünteti a némítást?
