Bias Calculator

Given below is the tube amp bias calculator to find the bias in ampere or milliampere (mA or A). Bias is an alternating current of high frequency which is applied to the tape recorder to reduce distortion. Tube bias of an amp is used to find the optimum setting for the flow of current in the tube when the amp is idling. Use this bias calculator to calculate the current based on the amplifier class type, plate dissipation, tube type and plate voltage.
