I am currently building clones of the KEF KUBE 200 equaliser
I want to find replacement OpAmps that are exact replacements for the now obsolete NE5532N or NE5532AN that can be sourced from Mouser or Digikey, not AliExpress

NE5532P or NE5532AP (which has slightly less noise than the NE5532P).
(You can find a thread about those going out of production, but in the end, they didn't.)

Not likely to show any audible improvement unless one of the 5532 is bad.
There are not many choices with much better THD or noise levels. 5532 was designed specifically for audio.
Opa2134 is jfet and somewhat better and still in dip8 package. Most new amps are surface mount.

Sorry, missed that however the problem remains that most of the new op amps that spec better then 5532 are surface mount. OPA2134 or LM4562 are good candidates. JFET may sound different due to much higher input Z.
Why not just use NE5532A in soic and use an adapter PCB ?

Because some people think that Onsemi is better than TI.

I still have Signetics, so I have not tried anything else.

Mouser seems to have a few in stock. 17,342 of them in the DIP package. They cost $.59 each in onesies! You might want to buy a few and perhaps some other assorted parts you will be needing to justify the shipping.
Looks good so far!
One tip I like to remind folks about… when using a soldering iron hold the end the cord comes out of!

It is normal to start a PCB assembly by mounting the resistors first. That way they will stay in place when you turn the through hole card over to solder them. Add parts smallest first or add smallest parts first!
Although you occasionally see images of someone holding solder in their mouth for some reason, it turns out there are other nicer methods to kill yourself!

Thank you everyone for your replies. It is appreciated. I know there are better OpAmps than the old 5532 but I will keep that one for the first "proof of concept" prototypes. I want a 100% original design to start.

You are 100% correct. But as I am designing a complete unit, I have to make mock-ups where mechanical components are only put in place, no soldered, to ensure my measurements are correct for the rear mounting plate and front aluminum fascia. Lot of back and forth. And yes, at the end, I shall start with resistances and caps, and end with quad RCAs, DIN connection and rotary pots.
Also, I'll be soldering sockets. Therefore that leaves a window for others for testing different OpAmps. In my situation, I don't want to change the sound from the initial design. I'll produce a faithfull copy of the KUBE 200, and a hybrid version with KUBE 107/2 Bass Extension Curve, but KUBE 200 Contour corrections.

NE5532 is still an active (i.e., current production) part at TI. They sell the National Semiconductor version.
It's actually a remarkably good part, especially for its age. You can find modern opamps that'll provide better performance and drop right into the socket. The LM4562NA springs to mind. But there's nothing wrong with the NE5532.

That's interesting. The NE5532A (also from TI) has a data sheet in the style of the old National Semiconductor data sheets. It makes me wonder who bought who at what point. 🙂

This might be in a circuit using a single OPA package. It falls down as soon as you have more than 1 package. Da new uber OPAs are all much more finicky about layout, decoupling bla bla such that swapping them for 5532 often (always?) results in WORSE performance.
Kingston, on GroupDIY had a thread on this for a large mixer with measured results.
This is specially true for LM4562. I can think of perhaps 1 application where this would be better and many where it would be worse. Apart from the layout, decoupling bla bla, LM4562 has a nasty habit of 'sticking' to the rails in many LF filter designs or single supply applications. Wayne Kirkwood investigated some of these nasties and IIRC, there is a thread in a NS or TI forum too.

You have some originals from Philips/Mullard hand carved by Southampton virgins ??!! 😱
But seriously folks. There are I think, only 4 sets of masks for 5532/34. The best by far were the Philips/Mullard ones which were bought by Signetics. Alas the great Southampton factory is no more
The TI versions were measurably worse. Dunno about NS. Doug Self made an amp from zillions of 5532 in parallel and measured all the versions for THD
My data is for noise. ALL Philips 5532/4s circa 1980 easily met the higher 5534AN spec. I must have personally tested at least a hundred.
Oh, interesting. The only opamp I've had lose its mind in a filter circuit was the OPA1611/12. It couldn't arrive at the correct DC operating point in a GIC-type filter. I popped in an LME49860 and it worked just fine. Go figure.
