I don't think the 6mV max input offset voltage of an opamp in this simple circuit will upset it since the circuit has up to 7V swings from the outputs of the opamps and many adjustment pots.
I think that you and have some different viewpoint about using 741 op amp, i don't know what to say, i'm a bit confused about that!!
The strange thing in this project is that it caused me to confuse and ask here about it although from the first look at it , i thought that it's very easy and not reserve such work..
any suggestion more will be appreciated!!
Your opinions are very important for me, thanks a lot!
