The 40 W XL Stereo Power Amplifier is an all vacuum tube design intended for moderate power output levels. A tube-based amplifier imposes some unusual requirements on circuit board design, notably high operating voltages and considerable heat from the active devices. The typical operating voltage of this amplifier (plate voltage) is 425 Vdc. To accommodate these levels, ample space must be provided between adjacent circuit board traces. The other design challenge is heat. Large vacuum tubes, such as those used in this amplifier, generate a considerable amount of heat. Check out more here.
