Sziasztok
Fent említett erősítőbe keresek HA 12017 című ic-t, ami a lemezjátszó előerősítőjében van (akár modult is).
Köszönettel: Csaba

Sziasztok.
A fent említett rádióerősítőt generálozom de lenne vele 3 problémám.
1: Raktam bele egy koppanásgátlót ami frankón működik is, de amikor a relé behúz (kb: 2mp után) akkor is koppanik a hangszóró.
2: Meg lehet-e valahogy szüntetni a sustorgó hangot a kimeneten?
3 Egészséges-e ez hogy a kimeneten terhelés nélkül 900mV-ot mérek?
A végfok kivan szerelve és úgy próbálom, úgyhogy a előerősítő + a szabályzó modul nem befolyásolja.
A 2200uF/25V-os kondikat már kicseréltem mert már eléggé ratyi állapotban voltak.
Kimeneten BD249, BD250 - es pár van.
Az infókat előre is köszi.
