  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
    analysis.

  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
    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.

    So people are supposed to play guessing games while you
    slowly dole out pertinent facts you have but hide from them?
     
  5. Travel Lightly and Swiftly: If all you carry is a hammer, the all your
    problems become nails and then they can all be solved by percussive
    maintenance (preferable preemptive).
