the Silver 7 prototypes used paralleled pair of A-451 outputs.
the Mk VI's used a model specific transformer that was never
offered as a catalog item. And it's primary impedance was
nomially 1650 ohms CT. As opposed to the A451's nim pri impedance
of 2200 ohms CT. The A-440 (and A-441) had a nom pri impedance of
4300 ohms CT and it is the 440 series that had the tertiary winding...
There was another Dyna output with a tertiary winding... though it never
went into production... the original tranneys developed for prototyping
the ST-70 amp had an ouput model A-460--- which had a 4300 ohm pri CT with separate screen windings.
