McIntosh Unveils MC3500 Mk II Monoblock: Updating the “Woodstock Amplifier”

This Mk II version of the iconic MC3500—the 350-watt monoblock amp model that powered Woodstock—is a fully updated take on a definitive classic tube design.

Woodstock 1969. Most attendees probably had something else on their minds other than what’s powering the show. But in the end, there’s no concert without power amplifiers, and the original 1968-1971 MC3500 monoblock is famously the model that drove the PA in the most famous concert of its era, if not in all of history. And now, after a 2-year development process inspired by the 50th anniversary of Woodstock (and McIntosh’s celebration of such) the company has announced the MC3500 Mk II, a $15,000, 350-watt tube monoblock amp that’s both a classic and full updated.

The new amplifier features modern components but also retains key aspects of the original design, such as the power supply (McIntosh’s Unity Coupled Circuit™ output transformer). It’s designed to deliver full power to speakers of varying impedance; you don’t get to use only half the power if you have, for example, 8-ohm speakers vs. 4-ohm.

“At the 50th anniversary of Woodstock in 2019, there was a lot of buzz resurfacing about the McIntosh sound system. This enthusiasm was infectious and inspired me to get our engineering team together to redesign the amp that has obviously resonated with music fans as being a historically significant piece of audio gear. After over two years, we are really proud of the result. The MC3500 Mk II takes its inspiration from the original 1968-71 MC3500 and incorporates all the knowledge we have gained surrounding vacuum tube amplifier design since the 1960’s.”

McIntosh President, Charlie Randall

A Better MC3500

This new amplifier is, as McIntosh describes it, “both modern and retro.” It features the U-shaped side rails that were a signature design element of the original and had the functional purpose of strengthening the chassis and making it durable for road use. Furthermore, on the rear of the amplifier, you will find the rubber bumpers that were a feature of the original, which allowed for vertical placement, as they were used at live concerts.

Of course, is a McIntosh, so you get an awesome power meter featuring the company’s DualView Power Output Meter design, which shows you both the amplifier’s output as well as tracking the amplifier’s warm-up time.

Pricing and Availability

McIntosh anticipates shipping the MC3500 Mk II during December 2021 in the United States and Canada. The rest of the world will have to wait slightly longer to get its hands on this historic, yet modern, and utterly impressive amplifier.
