McIntosh MA6
Little is documented about the McIntosh MA6. What the record shows is a specialized piece: a vacuum-tube power amplifier built around 6L6-GC tubes in push-pull, made to drive the 15-inch woofer section of the McIntosh ML-1C loudspeaker. It was part of a system approach that paired McIntosh solid-state electronics with the ML-1C speakers. Contemporary references call it simply a "special amplifier" for that job.
Past its purpose and tube complement, the paper trail goes quiet. No production years, original price or power output figures have surfaced in the available sources. No period reviews of the MA6 appear in the major audio publications of the era either. The model seems to have lived in the shadow of McIntosh's better documented amplifiers, a supporting part of the ML-1C system rather than a headline component. A period review noted the front panel measured 16 inches wide, and the chassis was 15 inches wide by 13 inches deep, weighing 34 pounds net (Modern Recording, February 1976, p.56).
Surviving information on this model is thin. What is known:
- Power amplifier, vacuum-tube design
- 6L6-GC tubes in push-pull configuration
- Built to drive the 15-inch woofer section of the McIntosh ML-1C loudspeaker
