hotwaterwizard, thanks for your comments!!....These number parts come from a Vintange solid state Ela Siemens Auso V75-02 unit , I found anything about this rare unit, you can see in the attached picture. I draw the schematic by hand but if you have the original schematic will be fantastic!!!!....These units(I have two of them) look like somebody pull out its input transformers.
I havent found them yet but Schematics are out there. A guy sols some on EBay with schematics and some are still for sale there too.
