I have two of these PP transformers from an old Magnavox hifi which were
used with a quad of 6V6s and decided to put them on the LCZ meter at
work and see how they behaved. First I figured out the turns ratio by
putting 10.8vac across the primary and reading .549 and .414 on the two
secondary taps. Dividing those you get 19.67 and 26.08. Square those
numbers and multiply by 8 and you get 3.095k and 5.441k. Look good so far?

All the testing was done with an HP 4192A impedance analyzer and the
secondary of the transformer shorted.

I started at 500Hz and went in 500Hz steps all the way to 20Khz while
watching the impedance and phase. Here is a chart from excel:

Now am I going about testing this correctly? Questions, comments?
