Use this calculator to determine the bias current for an amplifier’s power tubes. Enter the plate voltage and type of power tubes to get the bias current at various levels of plate dissipation. Amplifier Tube Values
26 lip 2001 · There is only one source of bias voltage, so the voltage at every tube's grid will be the same (it better be!). If you want to bias the amp properly, you will need either a bias probe, or a very good 1 ohm resistor and an equally good meter.
Tube Bias Calculator Instructions & Help. Enter values in blue and click any Calculate button. Select the Tube Type from the scrolling list. If your tube isn't listed then pick one with the same Max Dissipation Rate which is shown to the right in the tube list.
6L6GC Basing Diagram. 6L6GC Basics. The 6L6GC is an octal, beam power tube. What does that mean? The octal part tells us what kind of socket the tube plugs into. It has eight pins arranged around the circumference of a circle with a diameter of about 11/16 of an inch.
Bias voltage is the voltage difference between a tube's cathode and control grid. Bias current is the amount of electrons flowing from the cathode to the plate with no audio signal on the control grid (idle current). An amplifier tube controls the flow of electrons running through it.
With a properly biased amp, the amplifier will work more efficiently and will accurately amplify the sound of the guitar, pedals, and preamp. An incorrect bias setting can result in crossover distortion, inefficiency, and can cause damage to the tubes and amplifier. This guide will cover fixed adjustable bias amps.
