McIntosh MC-501 500 watt Monoblock Amplifier [Expired]


no longer for sale

This McIntosh MC-501 500w mono block has been used exclusively to drive the center speaker in my home theater system.  Using Audiogon’s definitions it is in very good condition having only a tiny scratch on the right side bezel.  I have the original factory shipping packaging as well as the owner’s manual.

To be clear, this is a single MC-501 for sale, not a pair.

I’ve listed a few of the MC-501’s key features taken from the Owner’s manual below; curtsy of McIntosh Labs: (I have and can send a .pdf of the owner’s manual if interested).

Ships to the 48 contiguous US states.

Power Output:

The MC501 is a Power Amplifier with a capability of 500 watts into 2, 4 or 8 ohm speakers with less than 0.005% distortion.

 

Full Balanced Quad-Differential Circuitry:

The MC501 is fully balanced from inputs to outputs. It consists of two matched power amplifiers operating in push-pull with their outputs combined in a McIntosh Autoformer. The double balanced configuration cancels virtually all distortion.

 

Patented Autoformers:

The McIntosh designed and manufactured Output Autoformer provides an ideal match between the amplifier output stage and speaker loads of 2, 4 and 8 ohms. The Autoformer also provides perfect DC protection for your valuable Loudspeaker.

 

Patented 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 Loudspeaker.

 

Patented Sentry Monitor with Thermal Protection:

McIntosh Sentry Monitor power output stage protection circuits ensure the MC501 will have a long and trouble free operating life. Built-in Thermal Protection Circuits guard against overheating.
