Problem wiz voltage regulator of PX200e Lusso E-start

I've got a big problem wiz my voltage regulator (foto under) which is down
My px is a german px200e (VSX1T) lusso e-start from 1978.
I'm looking for the same one but I don't find it in the SIP spare parts...

Who could help me ?


As no one else is helping[:)]

would have thought a rectifier, from most of the electric start/battery models, would fit.

unless I'm wrong[:$] but as long as it has the extra two connections should be fine
