McIntosh MC2205 Vintage Stereo Amplifier

$0

200W of American Muscle.

One of Mcintosh’s most popular amplifiers from the 1970’s. 

Built like a tank and sure to last 100+ years. 

Still relevant to today’s 200W amplifiers, and a solid reliable performer with a wonderful typical sweet McIntosh sound. 

This great and powerful vintage amplifier from McIntosh just received a light service from our in house guru and it came out beautiful.

This model is one of our best sellers and they dont tend to hang around very long.

We even upgraded to LED lighting to give it a fresher, more modern look, as most folks are disappointed with the original dim lighting on vintage pieces.

We can also supply a matching McIntosh wood cabinet for an additional $300 if you like the look.

Best of all it will ship in a brand new McIntosh double carton, the only way to ensure safe transport. Never ship one of these in anything other than that as it will result in disappointment.

Service Notes:
• Replaced meter lamps with cool white LED lamps
• Cleaned all front and rear panel controls
• Set bias to service manual spec
• Calibrated VU meters

Cosmetic Notes:
- Meter windows have some imperfections
- Some scratches on the tops of the transformers
- Faceplate trim bezel was removed but can be applied if desired (we and others feel it looks much better removed)

The SkyFi Testing Process for Solid State Amplifiers:
We start with a visual inspection of all internal components to make sure there are no signs of stress or aging. Capacitors are checked for telltale sings of bulging or leaking, resistors are checked for signs of overheating or cracking, and transistors are checked for signs of stress or damage.

We then power up the unit carefully and run a simple 1k sine wave while monitoring the output on an oscilloscope for signs of distortion or noise. Finally, we run the amplifier to its full rated power into the appropriate resistive load provided by our Sencore amplifier tester. If there is an issue, it will usually be noticeable at this point. If everything reads clean, we will often test for THD (Total Harmonic Distortion) measured by our Keithley distortion meter, and compare it against the original manufacturers specifications. The amplifier then remains powered on to "burn in" on our test bench for a few hours to make sure there are no heat related issues. If there are balanced inputs available they will be also be tested.

Final testing involves pushing actual music thorough the amplifier. We've learned over time that some issues are only noticeable to a trained ear while listening to familiar source material. Our test bench has reference vintage Kef speakers that we're very familiar with which quickly reveal any discrepancies. Some amplifiers will then move into our listening room where they are tested with our in-house reference speakers of choice.
