this is supposedly from a PREFM version of a show from 1978 that was later broadcasted
and yes i see the line just below 16k but theres also a secondary segment between 16k and 19k and i cant see obvious lego skyline

zoomed in spectral from cep

same with this one. taken from a different show. 1971. no obvious lego skyline and the dark part starts very low, though it seems more of a natural decline than abrupt change
any natural reason why a recording would seem to be so absent in the higher parts?

is this lossy?

don't know for sure about the first three, but that last one is lossy.
The second spectral don't look lossy, but it is missing a fair bit of top end.

Microphones may have had an upper range only up to 16K. Not very uncommon, some mini-microphones being used today top out at 16-18K.

First and last look bad, other two hard to tell without better info.
