What else to know about the McIntosh MC 2300?

"The MC-2300 is a solid-state power amplifier which was built by the American high-end audio company McIntosh, and sold between the years 1971 and 1980.[1] It can be utilized either as a 300-watt-per-channel stereo amp, or a 600-watt monoblock, and was rated by its manufacturer as being able to produce this amount of power continuously, with very little (less than 0.25%) distortion.[1] McIntosh's ratings were conservative, however, because like many of their amplifiers, when bench-tested the MC-2300 has frequently been found to produce an even higher level of clean power.2]

McIntosh MC-2300 Side

As such, it was ideal for use in demanding, professional applications. Most famously, the improvisational rock band the Grateful Dead employed 48 McIntosh MC-2300 amps as the main power source for their enormous public-address system, the Wall of Sound. Designed by Owsley ""Bear"" Stanley and others, this system utilized more than 26,000 watts of continuous power fed into JBL and Electrovoice speakers, and was renowned for its natural, low-distortion stereo sound which carried for 600 feet without significant degradation.[3] The Wall of Sound was only in use from March to October 1974.

In late July 1973, the Grateful Dead played at the Watkins Glen Summer Jam in the Finger Lakes region of New York State, along with the Band and the Allman Brothers Band. This concert was attended by 600,000 people - twice the number that went to the Woodstock festival in August 1969. Due to the crowd's enormous size, a significant number of concertgoers could neither see the stage, nor adequately hear the music projecting from it. Additional broadcast towers were set up, but this required more amplification power. Sound engineer Janet Furman was dispatched by helicopter with $6000 cash to nearby Binghamton, site of McIntosh Laboratories, to obtain five additional MC-2300 amps.[4] Despite the fact that it was the weekend, she was able to locate the owner, buy the amps off the factory floor, and fly back to the festival site, with the overloaded helicopter skirting high-rise buildings and narrowly avoiding catastrophe in the process. Thanks to a combination of persistence and luck, the extra MC-2300's were incorporated into the sound system, successfully providing high-quality music to the gigantic crowd.

Grateful Dead guitarist Jerry Garcia also favored the MC-2300, using one for many years in his own equipment stack." - Wikipedia
