Do you have or know where I can find a CD-1050 service manual?

Looking to do a NOS conversion. It has dual PCM56P DACs and what appears to be a discrete output section (no opamps visible on top of PCB).

The YM3414 (2-Channel 8-Times Oversampling Digital Filter) is currently in place.

OpAmp replacement

What case style is that IC120 position OpAmp?

Are there any newish and better OpAmps that are available as a straight swap.

Or is the OpAmp 8 pin and can it be replaced with a more common DIP OpAmp? Maybe even one side of a DIL OpAmp will align with the PCB holes and only the four other pins need to be straight wired?
