M c I n t o s h MC 2250 Stereo Power Amplifier250 250 Watt Per Channel prod. 1982 - 1988 1 out of only 499 units! This stereo amplifier is a serious piece of audio equipment. It is by far the most powerful amp that my home entertainment center has ever seen. The unit is about the size of an original XBOX, just alittle taller, but the MC 2250 weighs approx. 80 pounds! Ill include more detailed specs and information below, but in terms of my own experience with the unit; Sound: Exceptionally True, Full Resolution, Wide Soundstage with impressive seperation of vocals and bass, playback stays precise at low & high levels----no clipping or lagging or distortion whatsoever. Just smooth & powerful. Machine operates DEAD SILENT too! Physical Condition: Overall very good - great appearance. There are some hairline scratches and stubburn brushed-marks, and then theres maybe half a dozen more noticeable scratchesmarkings. Original Printed TextLettering is 96% Unscathed & Fully Legible, meaning less than 5% of the textlettering has been lost to time. Faceplate has one slightly bent corner, see photos, which is unfortunately not all that uncommon to see with heavy units like these. Interior is clean and well kept, wires kept tidy, surfaces shiny and connections secure. Metal frames and housings have very-very little to no rust at all. The photos should illustrate better than my words! ISSUE: The Red Light. Turn on the unit, and immediately the automatic system test sounds the alarm, (optional toggle off or on) indicates that there is something awry with The Left Channel (System Test code #3 blinks for a few seconds, it is faint, old bulb). Turn off the unit, wait a few moments and power it up again to find the same test code flashes, lighting up the red indicator for the left channel. HOWEVER, both channels are fully functioning and neither channel is operating differently than the other, if that makes sense. The left channel in this instance should be dead and or operate within a limited range, and the right channel should then sound significantly loudermore dynamic, simply in contrast to the left. But this is NOT the case. Fortunately, both left and right channels operate as they should, at low & high levels all the same. Unfortunately, there is a red light present alongside the normal green light. My guess is the left channel limit indicator has a faulty connection somewhere andor the corresponding IC chip (integrated circuit) component just needs to be replaced...or ignored!

This power amplifier delivers a powerful 250/250 watt output and features stereo L/R RCA audio inputs, 2 channels, and 2 inputs. Plus, it has a headphone jack and 4 outputs, making it the perfect addition to your home audio setup. With its sleek design and top-of-the-line features, the McIntosh MC2250 is the ideal choice for audiophiles who demand nothing but the best.

M c I n t o s h MC 2250 Stereo Power Amplifier250 250 Watt Per Channel prod. 1982 - 1988 1 out of only 499 units! This stereo amplifier is a serious piece of audio equipment. It is by far the most powerful amp that my home entertainment center has ever seen. The unit is about the size of an original XBOX, just alittle taller, but the MC 2250 weighs approx. 80 pounds! Ill include more detailed specs and information below, but in terms of my own experience with the unit; Sound: Exceptionally True, Full Resolution, Wide Soundstage with impressive seperation of vocals and bass, playback stays precise at low & high levels----no clipping or lagging or distortion whatsoever. Just smooth & powerful. Machine operates DEAD SILENT too! Physical Condition: Overall very good - great appearance. There are some hairline scratches and stubburn brushed-marks, and then theres maybe half a dozen more noticeable scratchesmarkings. Original Printed TextLettering is 96% Unscathed & Fully Legible, meaning less than 5% of the textlettering has been lost to time. Faceplate has one slightly bent corner, see photos, which is unfortunately not all that uncommon to see with heavy units like these. Interior is clean and well kept, wires kept tidy, surfaces shiny and connections secure. Metal frames and housings have very-very little to no rust at all. The photos should illustrate better than my words! ISSUE: The Red Light. Turn on the unit, and immediately the automatic system test sounds the alarm, (optional toggle off or on) indicates that there is something awry with The Left Channel (System Test code #3 blinks for a few seconds, it is faint, old bulb). Turn off the unit, wait a few moments and power it up again to find the same test code flashes, lighting up the red indicator for the left channel. HOWEVER, both channels are fully functioning and neither channel is operating differently than the other, if that makes sense. The left channel in this instance should be dead and or operate within a limited range, and the right channel should then sound significantly loudermore dynamic, simply in contrast to the left. But this is NOT the case. Fortunately, both left and right channels operate as they should, at low & high levels all the same. Unfortunately, there is a red light present alongside the normal green light. My guess is the left channel limit indicator has a faulty connection somewhere andor the corresponding IC chip (integrated circuit) component just needs to be replaced...or ignored!
