Neumann W491: asymmetrical bell shape after recapping - any ideas or service manual?

[Janus Audio]

Hi everybody,
I just finished recapping one of my two Neumann W491 EQs and unfortunately the mid band has an assymetrical shape now for some reason. Any ideads how this happened or maybe there is even a service manual around somewhere? The schematic I have already.

Thanks for your help!

If you have two of them have you compared them to each other?
