This is the McIntosh 4100 receiver. It was produced from 1978 up until 1985 and had a retail price of nearly $2000.00. The design seems to have a love-hate quality with audiophiles and collectors. Many think the design is ugly and don't like the plastic push buttons or lower quality veneer on the case. Others however, think the design gives it character and overlook any aesthetic weaknesses because of its fantastic sound. I believe it was the first integrated, solid state receiver offered by McIntosh which was known for their top of the line tube amps and tuners.
It's rated at 75 watts per channel in to 8 ohms or 100 wpc in to 4 ohms. It has some unique features such as the 5 band equalizer utilizing knobs as opposed to the more common sliders. It also has a loudness control that uses a potentiometer instead of a switch which means you can control the level of the loudness rather than just on or off.
It weighs roughly 42 pounds and measures about 18.6 x 6.5 x 12.5 inches or 472 x 165 x 318 mm.
Of course, it's a McIntosh, so it's very popular and in high demand. These receivers can sell for over $1000.00 in great working condition. Most sell for around $700.00 with even a parts unit selling for up to $400.00.
