Signal to Noise Ratio: greater than or equal to -90db.Frequency Response: 16 to 40 kHz, +0, -.1db 16 to 60kHz +0, -.5 db both at full rated power, 10 to 100kHz, +0, -1.0db at half rated power.Power: 40w/ch 4 ohms to 16 ohms and up to 125ohms to 600 ohms with minor reduction in power.Also the circuitry was unique, even today, in that it had the 6L6 power tubes cross coupled in a very tight embrace that gives very low distortion and amazing speed. The sound: Very lucid, extremely tight no matter what the load, and very fluid, due to its bifilar wound transformers (made in house by McIntosh) with their really wide frequency range. Bear in mind that this amp operates mostly in Class A, meaning it can put out 40 (stereo) to 80 (mono) watts into 3 Hz to 40KHz. Used as a mono block, it could put out 80w/ch. For instance it could handle speaker loads from 4 ohms to 125 ohms, even up to 600 ohms, all while putting out up to 40 solid watts per channel. The specifications on this amp are way beyond what you typically see today. It was bulletproof, capable of being used across a very wide set of impedances and crazy loads, with no degradation of sonics. It was typically used in theaters to power the big corner horns and other big horns used in those days. The McIntosh MC 240 was produced between 1960 to 1969, and was one of the last tube amps McIntosh made.
