Jack:
With regard to the plots under "Comparisons and Conclusions," and also under
"Frequency Response Compared," is it possible to change the source Z from
600-ohms to 50-ohms and re-test?
It would be an interesting exercise to see if THD (at ~ 1V RMS) and the
high-end frequency response of the Bourns transformer changes significantly.
Tnx!
Paul, W9AC

Subject: [Elecraft] K3 related - non-linear audio transformer behavior
I've spent the last two weeks measuring and analyzing non-linear behavior
of several audio transformers, focusing on the Tamura TTC-108 used as
isolation transformers in the K3.
My data and analysis is now available at
