As previous posters mentioned, your vintage Klipsch will pick up virtually any minor oscillations of the amp.
Technically I would experiment with adjusting feedback (obviously lowering the gain factor which may significantly help avoiding noise) along with adjusting bias current to the specified level of the THD which is more like re-tuning the amplifier.
