McIntosh MC302 Solid State Amplifier - WOW


Due to high demand and production delays, if you want a modern McIntosh amplifier this is your best route.

With the exception of a slight scuff on one end cap, this amplifier looks and operates like new.

It will ship in its original factory carton which is the only way to ensure safe transit.

Performance Features Include:
• Power Output
The MC302 is a Power Amplifier with a capability
of 300 watts per channel into 2, 4 or 8 ohm speakers with less than 0.005% distortion. The Power Amplifier Circuitry uses ThermalTrak1 Output Transistors for lower distortion and cool operation.

• Patented Autoformer
McIntosh designed and manufactured Output Auto- formers provide an ideal match between the amplifier output stages and speaker loads of 2, 4 and 8 ohms. The Autoformers also provide perfect DC protection for your valuable loudspeakers.

• Balanced and Unbalanced Inputs
Balanced connections guard against induced noise and allow long cable runs without compromising sound quality.

• Power Guard
The patented McIntosh Power Guard circuit prevents the amplifier from being over driven into clipping, with its harsh distorted sound that can also damage your valuable loudspeakers.

• Sentry Monitor and Thermal Protection
McIntosh Sentry Monitor power output stage protec- tion circuits ensure the MC302 will have a long and trouble free operating life. Built-in Thermal Protection Circuits guard against overheating.

• Special Power Supply
A very large Power Transformer and Large Capaci- tors ensure stable noise free operation even though the power line varies.
