It sounds like what you were describing is a technique using an HV CT power trannie, with a full wave bridge, which would then deliver 2X the DC voltage of teh standard 2 rectifier CT design, but at the cost of being able to deliver only half of the output current. This can use four SS rectifiers, or a tube rectifier for the + and two SS rectifiers (in a hybrid bridge) for the - side) The CT can then be used to deliver a half-B+ DC voltage, or can be left unconnected.
Been there, done that when a higher than "normal" B+ voltage was required...
