First time changing out DOD 250 IC's. What are my options?

Long time lurker, first time poster.  Great forum by the way.

Building an original DOD 250 Grey issue with the LM741 IC but have read this can be easily swapped for some other ICs.  Any one have any experiences or IC options I can try with this swap out?

Thanks in advance.

You can use essentially any sngle op-amp: TL071, TL061, LF351, NE5534, CA3140, etc.  No guarantee it will sound the same or better.
