In Reply to: What does DHT PP do differently/better then DHT SET? posted by Frihed89 on August 3, 2014 at 07:36:36:
It's possible that a PP amp operating in Class A might offer some benefit. In this topology, if the output tubes are well-matched, the instantaneous current draw from the amplifier's power supply essentially never varies. Filter caps are used primarily for filtering, and the need for the supply to provide a low Z path to ground over the audible frequency range is greatly diminished. Under these conditions, the power supply caps should in theory contribute much less of their own sound to the amplifier.
