This is a diamond in the rough. Some nice copper on it. Very hard to plit the cores! Epoxy ;-(

This is the dual C core transfomer I found cheap for winding a charge inductor

Rear view of LV feeds and lower HV star (wye) tie points.

Full view of HV taps and center points, I hope to wire a double Wye star!!

Important discovery on HV windings, There is a center point!!!

Diodes populated and ready for soldering will post finished product later.

First string populated The ends are +,- center is H1 they fit in my supply nicely

How I make the eyelett pcb for diode strings

Revised schematic sans tubes version 1

Closer shot of Inductor and secondaries.

I was happy to find a loose connection on the right standoff which was making that HV winding come and go with a DVM.

Inductor with pen for scale

Note the secondaries behind.
