McIntosh 20W

Not much is documented about the McIntosh 20W. What survives comes mainly from McIntosh's own advertising in the early 1950s, where the model appeared as the "20W-2" amplifier. High Fidelity (January 1953, p.130) carried an ad calling it a custom amplifier that delivers 20 watts, with 40-watt peaks. The ad also claimed acclaim from musicians, recording engineers, and critical listening laboratories. A similar ad ran again in High Fidelity (March 1953, p.26).

Beyond those advertisements, the Archive's record on the 20W is thin. No independent period review, full specification sheet, or confirmed production details have been found. Its exact relationship to other early McIntosh amplifiers is not documented.
