I can't really see what that diode and output-side capacitor are doing, not much I suspect. Your choice as to leaving them in place.

Thanks ... the center connection seems to end on this side but on the top side it is going into that diode + side... so bad that no one really has the schematic except one single person who wants 250USD for it ....
Thanks a million again for your help, will try and get a 7812 and see what I am getting then...
