MC3500 Vacuum Tube Amplifier Mk II

– 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 tubeamplifier design since the 1960s.

– 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.

– 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.

– Output powered by eight EL509S high-power output vacuum tubes, which was chosen specifically due to it having many similar qualities and
characteristics of the 6LQ6 “sweep tubes” used on the original MC3500.

– Like the original MC3500, the MC3500 Mk II has a fully balanced driver section that utilizes three 12AX7A and one 12AT7 vacuum tubes.

– Power Guard Screen Grid Sensor™ (SGS) helps prevent premature vacuumtube failure by monitoring the screen grid current in the output tubes. If the current becomes too high, Power Guard SGS dynamically attenuates the input signal in real time to keep the vacuum tubes operating at safe levels.

– Sentry Monitor™ observes the output current and shuts the amplifier off ifit ever exceeds safe limits.

– Uses a variation of our DualView™ Power Output Meter design, with thetop scale showing the power output in both Watts and decibels, while the bottom scale shows the amplifier warmup time.

– Front panel is machined aluminum with a bead blast finish and gold anodizing that emulates the look and finish of the original MC3500. A clear glass insert covers the meter; a black glass insert at the bottom houses the knobs and illuminated lettering.
