The following wave file contains a voice with a peculiar distortion.

I have viewed an oscillogram of the waveform and based upon the
asymmetry conclude that failure of one stage of a push-pull audio
amplifier caused of the distortion.

I would appreciate any comments and especially welcome further
analysis.


It sounds to me just like a narrow band FM radio system (typical analog
2 way radio) with an interferrinfg CW co-channel carrier that is a few
dB stronger and a few kHz off of the desired carrier...., you can
plainly hear the heterodyne.
