So they use one fixed bias, which is set at the factory. But pre-amplifier manufacturers assume that any tube of the correct type (12ax7, 6922, whatever the designer has decided to use) will allow the unit to run at a voltage and a current that are “close enough” to what the designer intended. Tubed power amplifiers always allow for tube bias adjustment. How Do Other Manufacturers Handle Tube Bias in Preamps?īefore we talk about preamps, let’s look at power amps. These incorrect operating parameters can affect sound quality. If your tubes are not biased correctly, your amp or preamp will run at incorrect parameters - specifically, a voltage and current that are different from what the designer intended. The result of our automatic bias adjustment: a circuit that brings out the very best from every tube you insert. Why is this important? Each pair of tubes requires slightly different bias. Adjustment is automatic, requiring no action on the user’s part. Our Rhythm and “Rhumba Extreme” preamps are the first ever to adjust tube bias, ensuring that your tubes are correctly biased at all times.
