The following are situations when biasing is needed.ġ. This allows maximum tube life and is far superior to any auto-bias system on the market, not just the 'Cathode Bias' based solutions.īiasing is a simple procedure requiring only one tool and a few minutes of your time. that all the tubes are pushing out approximately the same amount of electrical power. It’s that easy!īiasing is used to make sure the tubes are electrically operating in a similar manner, i.e. The needle moves slowly and exactly as you are turning it, so there is no guessing, when it shows the correct number stop turning, if you overshoot turn it back. Simply put, it’s turning a potentiometer screw clockwise or counterclockwise and setting it to the right number that is shown in the meter.

When customers hear us say that you’ll have to bias your amplifier under certain circumstances, there can be a moment of panic.
