djmk1988 Posted July 18, 2006 Share Posted July 18, 2006 Are cineva din intamplare un circuit dublu operational KM 157 UD 2 , de fabricatie ruseasca? Am nevoie de acest circuit pentru un magnetofon ROSTOV 105 s1, daca are cineva asa ceva , platesc in limita bunului simtz, sau daca nu are , macar ar putea cineva sa ma ajute sa fac o adaptare de doua operationala UA 741, sa le pot monta la Rostov?

Guest Posted July 22, 2006 Share Posted July 22, 2006 conexiunile le gasesti intr-unul din link-urile anterioare.157UD2 nu are echivalent direct.este AO dual cu compensare externa.Cele 2 AO incluse sunt fiecare asemanatoare cu LM301 (BM301).
