File photo for representation of item. May not be the actual item offered for sale.

This Amplifier was produced by McIntosh from 1993 until 1996 to commemorate the late Gordon J. Gow, McIntosh President from 1977 until 1989 and Vice President since the inception of the company in 1949. Mr. Gow was the co-inventor of the original McIntosh Unity Coupled Amplifier circuit. He was also the person most responsible for the unparalleled success and reputation of McIntosh Laboratory as the manufacturer of the world's finest audio electronics.

The overall appearance of the commemorative MC275 amplifier is very close to the original. It has the same dimensions, chrome chassis and black transformer housings. Several changes were made to the original design to take advantage of newer technology and accommodate the needs of contemporary sound systems.

  • Gold plated XLR balanced input connectors were added on the sloping section of the chrome chassis. This allows the use of balanced interconnect cables for lower noise and improved signal transfer. The amplifier sensitivity at the balanced input jacks is fixed at 2.0V for rated output.

  • An increase in gain was necessary to accommodate the balanced inputs. Circuit changes were made for this purpose, resulting in the change of four vacuum tubes. Each 12BH7 was replaced by a 12AZ7 and each 12AU7 was replaced by a 12AX7.

  • Two gold plated RCA unbalanced input jacks were placed on the front of the chrome chassis. Above these input jacks on the sloping section of the chassis are corresponding left and right volume controls. The sensitivity at the unbalanced inputs, with controls set at maximum, is 1.0V for rated output.

  • Two slide switches were placed below the balanced input connectors. One switch selects balanced or unbalanced inputs. The other switch selects stereo or mono parallel configuration.

  • Gold plated high current output barrier strips were placed on the sloping section of the chrome chassis. Output taps were provided for speaker impedances of 4, 8 and 16 ohms stereo or 2, 4 and 8 ohms mono.

  • The octal output socket that originally connected to the high impedance (500 ohm) transformer tap was removed. The 3 position lever mode switch, stereo balance control, twin amp volume controls, mono volume control and the twin amp input jacks were also removed.

  • Close tolerance film resistors, polypropylene coupling capacitors and fiberglass printed circuit boards were used.
