Inspired by the amplifier that inspired a generation.
There’s no denying the historic significance of the 1969 Woodstock Music and Art Fair. There had never been anything like it, and many would argue there’s not been anything like it since. With an unexpected crowd of over 400,000 people, there was a lot that could have gone wrong – and some things did. But one aspect that’s nearly universally agreed upon was how great all the musicians sounded. That sound quality is thanks in part to the McIntosh MC3500 Vacuum Tube Amplifiers that exclusively powered the sound system used at Woodstock.1 The MC3500 would go on to power many other influential music events.
Our exclusive Power Guard Screen Grid Sensor™ (SGS) technology is included in the MC3500 Mk II. Power Guard SGS is designed specifically for our vacuum tube amplifiers and similar in nature to our patented Power Guard® technology found in our solid-state amplifiers. Power Guard SGS helps prevent premature vacuum tube failure by monitoring the screen grid current in the output vacuum tubes. If the current becomes too high, a circuit in Power Guard SGS is activated which dynamically attenuates the input signal in real time to keep the vacuum tubes operating at safe levels. The fully balanced driver section of the MC3500 MK II is an ideal match to use with Power Guard SGS. Sentry Monitor™, which observes the output current and shuts the amplifier off if it ever exceeds safe limits, is also included.
Both a balanced and unbalanced input are included for connecting to your preamplifier and the rest of your home audio system. A balanced and unbalanced output are also included for multi-amp configurations, such as bi-amping or tri-amping.
