The amplifier uses a pair of 6H30 lamps at the input and four KT150 lamps at the output. In addition to the KT 150, the amplifier can work with other lamp options, including the 6550, KT88, and KT120. A fan is built into the protective cover to cool them. The power supply unit uses a high-power power transformer with high-capacity capacitors, providing "extremely high current for transient peaks and intense dynamics, as well as amazing depth and bass power."
