The MC3500 Vacuum Tube Amplifier Mk II is a conservatively rated 350 Watt monoblock that takes its inspiration from the original 1968-71 MC3500 and incorporates everything we have learned about vacuum tube amplifier design since the 1960s. It has been upgraded to modern standards and with modern components to deliver an audio performance worthy of its predecessor and the legacy of their shared model number – all while adhering to the original design as much as possible. Like the original MC3500, the MC3500 Mk II uses our Unity Coupled Circuit output transformer, which allows the full 350 Watts to be safely delivered to virtually any speaker regardless if it has 2, 4 or 8-Ohm impedance.
