Hi SuperB,Jonathan went through a number of winding geometries in an effort to optimize both the sonics and the measured response. The Mk I had a substantial peak somewhere between 50 and 60 kHz. The Mk II doesn't have the peak, and rolls off between 90 and 100 kHz.
Among the many prototypes and early units, some have single primaries while others have dual primaries, allowing a +6dB option. The Mk II has dual primaries (though mine are internally connected in series).
Below is a link to the Bent Audio Forum on Harmonic Discord. John Chapman maintains this site for discussion of his products, especially the S&B transformers.
