I have these opamps in a PSU with a fairly high voltage at +/-21.5V. Are there any suitable replacements capable of surviving this supply voltage? I am looking for a wider bandwidth and higher slew rate.
Thanks

nice specs.
unlikely to be a drop in replacement.
Probably requires careful placement of decoupling capacitors and maybe additional stability compensation.
Is noise a concern?
Is the change to FET a concern?

They are used in SIP8 packaging. I ordered some DIP8 to SIP8 conversion boards that have some prepared room for decoupling and/or compensation caps. I will see what can I do when I get them.
No concern - the circuit is from pre-amp section of Marantz PM15S1 - very nice components throughout plus their HDAM modules. It looks ugly with such low spec opamps. I guess I am trying to improve things that can be improved.

The NE5532 is already a pretty good opamp, just cheap because so many were made.
One is a unity follower and one is just a dc integrator, so neither in a stressed position
