Modern pre-amp IC 7 pin in line?

I'm rebuilding a Sansui AU-5500, I came across an IC, BA312 manufactured by Rohm. It's a Dual preamplifier from the 1970s, it has 7 pins inline so I'm wondering if anyone knows of a modern drop-in replacement with better specs or just sounds better? Its the pre-amp for the phono section by the looks of the schematic, I started looking for a suitable replacement then thought I would ask you guys who are much more experienced than me! :D

I found this works in many instances and many have the parts on hand.
