| Bias King The bias of tubes is critical (learn more about bias) to the sound of an amplifier and the life of its tubes. The Bias King includes directions to take simple readings for the most commonly used power tube types (6V6, 5881, 6L6, EL34 and 6550). With the Bias King, it's easy for you to keep the bias of your tubes perfectly matched. It's simple to spot fading tubes, keep your amp perfectly tuned, and always ensure your listening experience is the best it can be. Please note that the Bias King requires AC power on the tube's heaters. Most home audio amplifiers use DC power; consult your manual to confirm how your amp works.
