Interesting Output Stage?

[Synchrodyne]

Another possible pathway to applying U-L to an orthogonal amplifier would be to use a separate screen grid primary for the push-pull transformer, and take the centre-tap from this to an appropriate primary tapping (or to a separate winding) on the single-ended transformer. This way distributed loading would be maintained for all input signal conditions. But that is possibly getting into self-defeating complexity.
