Therefore if used within a Class AB amplifier and power output is increased the high voltage supply (HT) will sag or drop in voltage as the amplifier load or output increases, adding distortion, compression or sag to the output signal.
Therefore if used within a Class AB amplifier and power output is increased the high voltage supply (HT) will sag or drop in voltage more so with a tube rectifier. As the amplifier load or output increases this drop will add distortion, compression or sag to the output signal.
