Greetings all !!! i have a question for the masses. i am butchering a vintage dj mixer. and need a bit of advice. i am replaceing the phonopreamp IC which is a intersil corp 4741-5 (quad 741). I am thinking of brownies opa404 or the 4227. Also to be replaced is a raytheon Rc4558 (in line siganl path)with B. brown 2227 and a 741 with a opa627 (may be a bit overkill.) so are the 2134,4134 better choices than the 2227 4227?
last i have a few chips i cannot figure out what they are
CA3080
1556 827LF
1556 356N
820 LM377N
any comments or suggestions would be appreciated
thank you
