    McIntosh MC501 Mono Power Amplifiers!

                             Serial Numbers WU3876, WU3877  Sold as a pair.

These amps are in great condition cosmetically and functionally and look new. Each amplifier produces 500 amazing watts and has the Classic looks to die for.  This pair is nearly mint, and works without any issues.  This amp is simply spectacular and deserves to go to a good home!  The amplifiers comes with the power cord,s original boxes, and manuals. Ready to be shipped.  Feel free to ask any questions.



The design of the MC501 is straightforward and extremely burly. Not only is the amp capable of delivering 500W into any load between 8 and 2 ohms, it's also rated to deliver more than 100 amperes of output current. It seems exceedingly unlikely that there is a speaker that the MC501 could not drive.
