This runs the A440 with its ~15% tertiary winding.

It is IME far better to run it with CFB, and *THAT gives also the same percentage of U-L with a fixed g2 voltage applied.

The PP split load amplifier is entertaining for sure.

The CFB gets us short-loop NFB and avoids the loop. That IME is not as satisfying to listen to.

Sorry, ultralinear, not unity coupling.
