The MC70 70th Anniversary Vacuum Tube Amplifier is a 150 watt per channel stereo amplifier, featuring a striking design to celebrate seven decades of McIntosh handcrafting some
of the best home audio equipment the world has ever heard. The MC70 incorporates lessons learned and the techniques invented through 70 years of audio engineering. Utilizing patented Unity Coupled
Circuit output transformer technology, the same technology the company was founded on in 1949, the full 150 watts can be delivered into almost any pair of speakers, regardless if they have 2, 4,
or 8 ohm impedance. This stunning design is highlighted by a bead blasted black anodized aluminum chassis accentuated with matte finish carbon fiber side panels. The front panel showcases a backlit
laser cut McIntosh logo flanked by gold accent McIntosh knobs. The vacuum tubes are covered by a removable 12-gauge stainless steel wire cage with a black powder coated finish.
The MC70 uses eight KT88 output vacuum tubes plus eight small signal tubes comprised of four 12AX7A and four 12AT7 vacuum tubes; half of the tube complement is assigned 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. The LEDs under the eight small signal tubes can be set to
three illumination settings: Off (which allows the tubes natural amber glow to be visible), Green or Blue. Sentry Monitorâ„¢ technology monitors the output current and shuts the amplifier off
if it ever exceeds safe limits.

On the back are balanced and unbalanced inputs, along with patented Solid Cinchâ„¢ speaker binding posts to securely connect your speaker cables to your speakers. An input and output
for Power Control technology will automatically turn on or off other connected McIntosh components such as preamplifiers, CD players or turntables.
To the back are the two Unity Coupled output transformers with the power transformer centered between them. All three transformers are housed in glass topped extruded enclosures
with gold accents displaying the wiring diagram for each transformer.
