replacing RC4136 opamp w/ 2 OPA2134 on DIP pinout adapter board

I've made a lot of improvements to my old Soundcraftsmen DX4000 preamp, like enclosed the power transformer in a cage and upgraded the filter caps, and replaced all the twisted pairs with shielded wire, added balanced output transformers and a variety of jacks...

So replacing all the obsolete slow RC4136 opamps is long overdue.

For a long time I'd been planning to use a DIP pinout adapter from Brown Dog to mount two OPA2134

Is there anything newer / better to use that I should be aware of?
