WebMay 11, 2013 · When biasing a tube, you want to know the *current*. You need an *estimate* of the voltage to design your bias supply. If a tube needs -12V, it might be silly to build a 100V bias supply. OTOH if the tube needs -85V (some do!), then a 50V bias supply is not going to do the job. Some tricks: WebMay 19, 2024 · The reference inductor was measured with DC bias using the J2121A in accordance with the methods published in this article. The impedance, measured at 0.1 Amps and 20 Amps, shown in Figure 1, confirms the inductance is stable up to 20 Amps. This is well above the DUT’s operating current. The measurement starts to get noisy … graham advisory network incorporatedWebCathode to plate current is controlled by the control grid voltage. Voltage is easy to measure, and the bias adjustment potentiometer is most likely adjusting this negative voltage. A higher negative voltage will bias the amp "colder" by lowering the idle current. A lower negative number will bias the amp "hotter" by raising the idle current. graham a fordyce
