I was just thinking, how about a pair of heavy diodes back to back across the filaments and pull the D.C. from the center tap. If I'm thinking correctly, they could be low voltage silicon jobs. Hmmm. Better draw that out on paper and chase current flow.

Hi John, good idea thanks, this rig comes with this transformer installed, but after so many years who knows if this transformer works or was the cause to discard the BC610.
Maybe Im go solid state all the PS at once, after all, I have to be sure when running 2500V DC isn't?, its more easy than try to found an original filament transformer anyways
thanks again an have a nice weekend John!
