Webb27 nov. 2024 · Looking to stock up on some 100k plate resistors. I was looking into the wattage and voltage ratings. For instance the Vishay PRO1 metal film resistors are, while rated at 1 watt, have a max voltage ratings of 350 volts. I would think this resistor would be plenty acceptable for a third stage plate Resistor in the ab165 bassman I'm working on. WebbThis calculator uses the power equation. P = I × V. P is the power rating of the power tube, I is the bias current, and V is the plate voltage of the power tube. Solving for I we get. I = P V. When biasing to 70% or whatever percent you’re looking for you simply multiply the answer by that number divided by 100. We’ll call this variable x.
