I was thinking...If you were to do this again with modern equipment,
you could play the test tone out through a channel of a DAW interface
and simultaneously record the result back into an input on said same
DAW. The resulting recording would be sample-synchronized to the
original test tone file due to both converters running off the same
clock. You could therefore use a mathematical subtraction of the
original test tone so that the removal of the original test tones would
be complete, and without artifacts.
If this works, it would enable the kind of real-time circuit tweaking
that some of us feel defines "Hands-On" electronics.

Fooling with -90 signals might require shielded gloves, though...
