Anyone got the Braun 4737 schematic?

The 2 AA NiCd cells died, I've hot bags of AA NiMh cells but the shavers
charging circuit isn't having any of it and its proving a challenge to round
up AA NiCds from the spare battery box with much capacity left.

The schematic would allow me to figure out whether its possible to modify
the charging circuit to suit NiMh.

Thanks.
