You don't believe starting an amplifier that has no step start on the higher
voltage portion of the transformer to be a problem?
Think about it. Less windings in the CW position increase the turns ratio,
increasing high voltage.
What would be less prone to having stress induced on it during a startup? A
transformer with 20 turns, or one with 30 on the primary (the numbers are
arbitrary). What would have less stress induced on the rectifiers? E*I=W,
and if you increase the E, then the amount of W increases as well.

Anything that keeps the equipment stock, or able to return to stock is the
best solution
