  1. 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

  2. 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.
  3. I agreed that improper design of a single-ended stage would cause

    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.

    So people are supposed to play guessing games while you
    slowly dole out pertinent facts you have but hide from them?

    problems become nails and then they can all be solved by percussive
    maintenance (preferable preemptive).
