So I would need a power transformer with three secondary windings: a 320 VCT, a 6.3 volt with no CT, and a 25 VCT? Like I said, that is pretty specific. Sounds like unobtainium to me. Could I get close to 320 VCT with a 6.3 volt winding and also run a second power transformer with a 25 volt, center-tapped secondary? Like this one (assuming the amperage is sufficient).
