"WebIf the parafeed coupling capacitor is correctly chosen, and if the speaker impedance is nearly resistive near the low frequency cutoff, the tube can be made to see a nearly resistive load to a lower frequency that one would calculate from the inductances alone. This smaller phase shift reduces tube-generated low frequency distortion., giving a ... " - Parafeed set
