Another suggestion is to try the NJM2068, or NJM2114, are what I often use to replace the NE5532 most of the time.
My apologies if you are bound to using the older part in older equipment.

Mountainview components is offering Philips NE5532A that he says were manufactured in 2016. Is that possible? I have read that the Philips factory in France burned down in 2003.
Not to mention that Philips Semiconductor have been called NXP for about as long. (BTW, I don't think the whole factory burned down, but there was damage to that production line. That also cost us their BD139/140, though the same die in surface mount packages is still available from NXP.)
Looks like Signetics / Philips parts had a date code in yyww format. Looking up some pictures, the latest I've seen indicated 01, with plenty from about the mid-'80s through the '90s.

Which would be 1995, when the company was called Philips
Thailand would be the packaging and test location
