“The sound that inspired a generation”: an original pair of McIntosh tube 350-watt monoblock amplifiers, circa 1968 – 1971. This amp was famously used at the 1969 Woodstock festival.


    Need to drive a difficult load? With the MC 3500, no problem!


    Everything old is new again: McIntosh has reissued the MC3500 in modernized form at a retail price of $15,000. Photos courtesy of Howard Kneller, from The Audio Classics Collection.


    1963 Calrad catalog cover. Simple and to the point, though it probably didn’t win any design awards.


    Mullard tube ad, circa 1920s. “P.M.” stands for “Philips-Mullard.” They knew how to make tube filaments in those days!
