However, my question is about how you would use a 1950s era scope
to determine a sine wave or the degree of harmonics present.

Scopes from that era easily reached several MHz of bandwidth.
That should be considered adequate to inspect audio signals.

Cheers!


The eyeball is a really lousy detector of harmonics, though, especially
odd harmonics.

Plus he had to use a 1950s-era microphone, so the scope bandwidth is
irrelevant.
