WebJan 14, 2024 · Using Hall Amplification, you can obtain a variable voltage regulator (VVR mod). It is critical that a vacuum tube is biased so that it can be used as an amplifier. When cathode-biasing occurs, we connect a resistor between the cathode and the ground. After that, we ground the grid (with a large value resistor) to a negative voltage.
