Mcintosh MC2102 Tube Amplifier With Custom Cover

Free Shipping on *ALL* Electronics (Excluding Speakers, Contiguous 48 US States Only)

If you like the MC275 then you'll LOVE this MC2102.

The MC2102 features a similar design and topology, but with a bit more power and a better looking form factor in a traditional chassis configuration. 

Best of all it sports the legendary McIntosh meters on the faceplate while still showing off the glow of the tubes through a viewing window.

This particular sample is in excellent condition. The only noticeable signs of use is that both of the meters have lightened in the middle presenting a sunburst look.

Tested on our bench to full working power without issues. Visual inspection shows that all caps and internal components are healthy.

Includes a custom made dust cover to keep it looking new.

Our Testing Process for Tube Amplifiers at SkyFi:
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 tubes are inspected for signs of stress overheating or cracking.

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 it all looks 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 the 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 also be tested.

We also test all tubes for output gain and leakage on our modern and professional tube tester against the original manufacturers specifications. If needed, the tubes will be replaced from our vast NOS (New Old Stock) vintage or modern inventory.

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.
