No mid-fi, no gimmicks, no junk. Each piece of equipment is cosmetically restored and fully tested in our well-equipped lab by an engineer with 30+ years of experience in the HiFi world. Through our sister company, which is an authorized dealer for McIntosh, Audio Research, Sonus Faber, ClearAudio, Project, and Sony ES, we have access to OEM parts, service, and support. We’re pleased to offer this Super Rare 220V version of this American legend. Even rarer to find one in this chrome is simply gorgeous, and the paintwork is superb. Plus this vintage tube amplifier received a complete internal restoration, bringing it to better than factory specs and reliability, while delivering the original sound signature that McIntosh intended. We achieve this delicate balance by upgrading components that don’t affect the sound quality, while keeping the ones that do. If you live overseas and have wanted a McIntosh tube amp, this is the only way to avoid using an external voltage converter which tends to be a huge compromise. Plus this MC240 is fitted with a complete set of vintage tubes to boot! Configurable for 240V or 120V operation upon request. Includes a very high quality custom embroidered dust cover. Fully Restored: Power Supply was completely rebuilt with modern components. Select Resistors replaced on tag boards. All original red line Sprague difilm caps left in place, all high voltage Bumblebee caps replaced with Paper in Oil caps. Original Bumblebee input caps left in place. Because this unit has a 120/240 transformer, the 125V/117V AC Voltage selector switch was repurposed to act as a power On/Off switch. Telefunken 12AX7 Smooth Plate (V1 – The critical first tube shared between L/R Channels is perfectly balanced). Philips NOS JAN 5814 (Military Spec 12AU7 Sub). 6L6 – Current Production Tung Sol Reissue 6L6GC. 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 modern professional. 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. If we dont have the original manufactures packaging, we use heavy duty double-ply corrugated boxes with custom made to your item Instapak expanding foam custom inserts. In many cases this has proven to be better than the original packaging! We also use high quality fiber reinforced tape to seal our packages.
