Default Op amp in Rotel RB985MKll

Hi All
Not brill with electronics.Think the 4558 in the input of the Rotel multichannel 985MKll is being used as a level adjustment(as there is a d sub 25 on the back to do that)
Any suggestions on an upgrade for the op amp?
Ta for any help

That circuit you show is the protection relay circuit. If it works there is no advantage in changing it. 4558 and that type of op amp are very reliable and good quality.
