Jack,
Could you do me a favour please? I'm interested in what happens on the
headphone output if you re-run the tests using a 2.7 or 2.8kHz filter with
the audio tone set low enough in frequency so that the 3rd harmonic lies
within the filter passband (i.e. below 900Hz). I use the Heil phones which
have a 200 ohm impedance so if you could use that as the load that would be
great.
Thanks (if you can do this)
Regards,
Paul M1PAF
