This story is particularly interesting since in the same era, and even much more recently, most amplifiers that are anything other than "low end" have a muting relay, primarily for speaker protection, because the two supply rails do not always move at the same rate. If that relay were present, the shutdown could have been done after the protection relay was dropped out, and the glitch would have been silenced. Evidently the system described did not consider speaker protection a thing worth providing.
