Hi,
I tried to make an AC diffirential amplifier using an opamp (741).
I try to use the ordinary opamp differential amp circuit that usually
appears in the book and in the internet but it doesn't work. I also
try to put a C block the DC but it also doesn't work. I wonder that
anyone can point me out?

Thank you

Point me toward the "ordinary opamp differential amp circuit that
usually
appears in the book and in the internet", please. Perhaps we can
figure out why it didn't work for you.
