McIntosh Reissues Tube Classics MC75 and C22

Since 1947, when McIntosh introduced its power amplifier design using its patented bifilar-wound dual-primary output transformer, the brand’s power amps have been considered the performance standard. The MC75 in considered one of the best tube classic amps of all times, while the C22 Preamplifier is the perfect “control center”. Now McIntosh decided to bring back those two classic designs.

Here’s a do-it-yourselfer’s dream in tube amp design: four operating modes, high quality, low cost, and low distortion. An article originally published by audioXpress in May 2007. A true versatile project which we think deserves to be shared.

Tube life can be extended if you delay the application of high voltage until after the heaters have warmed up and current can flow. This little module does just that: depending on the setting of a jumper, it delays the high-voltage for 40 or 60 seconds after the amplifier is switched on. And the module is available as a kit.

Designed, manufactured and assembled in England, the new Tron Atlantic high end amplifier combines an affordable price with a compact chassis not compromising on big sound. The Atlantic is an extremely low noise stereo 300B design with a D3a driver stage, delivering 9 watts per channel with 4, 8 and 16 ohm outputs.
