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.
TIA

A single-ended bipolar transistor stage with no standing current will also produce this sort of sound. It's half-wave rectified, somewhat biased off.

I agreed that improper design of a single-ended stage would cause distortion.
However, an earlier portion produced by the same equipment contains a mid sentence transition from symmetrical to asymmetrical audio accompanied by a loss of volume.
