Binghamton, NY – August 6, 2020– McIntosh, the global leader in prestigious home entertainment and ultimate-quality audio for 70 years, is proud to announce the MC1502 Vacuum Tube Amplifier. The 300-Watt vacuum tube amp in the MC901 uses McIntosh's patented Unity Coupled Circuit output transformer. The MHA200 uses a pair of McIntosh's Unity Coupled Circuit output transformers to deliver pristine audio. The Unity Coupled Circuit is the same technology McIntosh was founded on in 1949 and is still used in their home audio vacuum tube amplifiers such as the timeless MC275 and the more recent MC1502.

Although Jefferson was at the cutting edge of transformer design technology in 1936, it set the stage later for Frank McIntosh to develop the Unity Coupled transformer that enhanced power amplifier performance with wider bandwidth and lower distortion. Both Jefferson and early McIntosh amplifiers use 6L6 output tubes.

McIntosh is proud to announce the MC1502 Vacuum Tube Amplifier - a stereo amplifier designed for home audio and home music systems that produces 150 Watts per channel. It is the direct replacement to McIntosh's award-winning MC2152 Limited Edition 70th Anniversary Vacuum Tube Amplifier, which had a limited production run in celebration of their 70th Anniversary that occurred in 2019. The new MC1502 has identical audio specifications and sound reproduction performance of the heralded MC2152 but in a more customary McIntosh design.
The MC1502 shares the timeless styling of their classic MC275 Vacuum Tube Amplifier. As the MC1502 has twice the stereo power rating of the MC275 (150 Watts vs. 75 Watts) and is physically larger, in many ways it can be considered the MC275's big brother. And while a pair of MC275s can be run in mono to achieve the 150 Watts per channel output of the MC1502, the MC1502 boasts a better signal-to-noise ratio of 112dB vs. 105dB for the MC275 pairing - producing an even quieter performance than the already quiet MC275.

The MC1502 is powered by eight KT88 output vacuum tubes, with four assigned to each stereo channel. It also has eight small signal tubes, consisting of four 12AX7A and four 12AT7 vacuum tubes; two of each of these vacuum tubes are dedicated to each audio channel. The 12AX7A vacuum tubes are for the Balanced and Input amps, while the 12AT7 tubes are for the Voltage and Driver amps. All the vacuum tubes are covered by a 12-gauge stainless steel wire cage with a black powder-coated finish.
The KT88 vacuum tube sockets include Air-Pipe cooling at their bases to help facilitate long service life. The eight signal tube sockets have ceramic base construction with gold plated contacts, providing protection from atmospheric contamination. All the vacuum tubes sit atop the precision formed stainless steel chassis polished to a mirror finish. McIntosh's Sentry Monitor technology monitors the output current and shuts the amplifier off if it ever exceeds safe limits; the signal tubes will flash red if Sentry Monitor is ever activated.
Unlike many other amplifiers, the MC1502's full 150 Watts can be delivered to almost any pair of speakers regardless if they have 2, 4 or 8 Ohm impedance. This is thanks to McIntosh's patented Unity Coupled Circuit output transformer technology - the same technology McIntosh was founded on in 1949. Two Unity Coupled Circuit output transformers flank the power transformer which is positioned between them. Each transformer is housed in a glass-topped extruded enclosure that displays the wiring diagram for each transformer. Two fully spelled out vintage die-cast aluminum name badges adorn two sides of the MC1502, while an abbreviated badge is centered between the Tube Lights and Power knobs.
Both balanced and unbalanced inputs are included to connect the MC1502 to your preamplifier and the rest of your home audio system. McIntosh's patented Solid Cinch speaker binding posts will securely connect your speaker cables to your speakers. An input and output for McIntosh's Power Control technology allows other connected McIntosh components, such as preamplifiers, CD players, turntables, or media streamers, to automatically turn on and off.
