I am looking at building a SET amp with some sort of voltage regulator as the last stage. I have read that a good voltage regulator can provide low impedance over the entire frequency range vs a capacitor.
I have been looking at using a simple shunt regulator with a CCS and a couple VR tubes in series. However I have read that while VR tubes have negative DC resistance, they do tend to have higher dynamic impedance.
Can someone confirm if this is true, and if so, does anyone know exactly how much impedance they might have compared to a ~100uf capacitor?
Ultimately I am trying to find a voltage regulator that has a consistently low impedance that is independent of frequency.
