2043DD JRC op amp

[diko2]

Hi,

On the master section of my Soundcraft 8000, I've found two 2043DD JRC op amp.
When i compare with the schematic, one is taking place instead of a 5532  and the other one instead of a TL072.
I don't find much info about those 2042DD.
Any infos about those?
Is it usual to find different op amp from the schematic?

Thanks

Morgan
