McIntosh MC75 Anniversary Edition Tube Monoblocks - Super Collectible!


Super rare and collectible Anniversary Edition monoblock amps from McIntosh commemorating their 60th anniversary (1949 to 2009).

These were released in very limited quantities in 2009 and quickly bought out by collectors.

Finished in a gold plating they sure look amazing, and will fit in with just about any vintage system.

They're also great performers just like the many generations we've seen in the now 70+ year span.

Whether you're going to stash these in a closet where they will outperform the S&P or use them daily, here's your chance to own a piece of history.

We actually have two sets thanks to some recent luck, so we're selling these and keeping the others for the moment.

Both of these MC75's were tested in our lab and working perfectly as you would expect.

They will also come to you complete with their original owners manual, foam tube blocks, and all official McIntosh cartons and packing.

SkyFi Cosmetic Notes:
• Very tiny mark on the top of one of the power transformers.
• Missing cage screws (May be available from McIntosh if you really wanted them).
• Very light marks around jacks.

The SkyFi Testing Process for Tube 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 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 calibrated 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.
