The amplifier circuit doesn't have the usual catching diodes from the output to the power rails that are usually fitted to limit transients should a speaker be disconnected while in operation.
Maybe not having transient protection is a MacGuffin for audiophiles? or a cultural/religious thing for the designer? or maybe they found ludicrously high voltage transistors to be cheaper than a normal transistor plus a diode?
A look at the circuit while asking the question 'Where could such voltages come from?' gets the answer 'Only from outside' and suggests that some more reasonable transistors, plus a couple of fast diodes would do the job better.
