Fusion Monoblock Tube Power Amplifier


The Fusion Monoblock Vacuum Tube Power Amplifier comes complete with power, punch, and delicacy. The 211 tube was selected as the main power output because of its long life and value price as an industrial heating tube (10,000 hours and $60). The Fusion provides so much weight in the bottom end that a powered subwoofer is irrelevant. The highs are extended with no loss of the delicate harmonics or air. In terms of power, the Fusion can handle speakers down to 80 dB sensitivity. For safety, the Fusion has a digital protection circuitry, which can handle surges from the outlet or internal short circuit should a tube fail. High quality construction and parts will contribute to years of pleasurable music.
