Taking retro design cues from the legendary McIntosh MC275 Vacuum Tube Amplifier, the MA252 combines the best of vacuum tube and solid state circuit design to create an amplifier that’s both visually and sonically stunning. The preamplifier stage uses two 12AX7a and two 12AT7 vacuum tubes housed inside stylish protective cages; the output stage is a direct coupled solid state amplifier that delivers 100 Watts per channel into 8 Ohm speakers or 160 Watts per channel into 4 Ohm speakers. An all analog design, it comes with 2 unbalanced, 1 balanced and 1 Moving Magnet phono input for turntables. All 4 inputs can be given user-friendly names in order to simplify user control.

Thanks to its solid state output, the MA252 is the first McIntosh product containing vacuum tubes to include our patented Power Guard® technology. Power Guard monitors the output signal for signs of over driving and makes real time micro adjustments to the input signal to prevent harsh sounding clipping that could potentially damage your speakers. If Power Guard is activated, the 2 vacuum tubes connected to the affected audio channel(s) will flash an amber color; they will return to their normal green color when the clipping has stopped. Other McIntosh technologies found in the MA252 include Sentry Monitor™, High Drive headphone amplifier and gold-plated speaker binding posts. Input selection, bass, treble, tone bypass, balance and input offset levels can be adjusted using the front panel knobs or the included remote control; all settings and input selection will be shown on the OLED display.

If you are looking at this Im sure you know what it is. I wont bother listing its specs -- as you can find that online. It is in excellent cosmetic and working condition. The only issue I see is that some of the lettering has come off. The lettering under one of the tubes and the word over the volume control are missing. See pics. Included (along with the original Mac tubes) are a pair of nice, matched pair of Genelex Gold Lion 12ax7 tubes and a wonderful matched pair of vintage Telefunken 12at7 tubes. I bought the Gold Lions from Upscale Audio and I believe I bought the Telefunkens from Viva Tubes. Both quality vendors. Also included is an upgraded W Audio power cable. The MA 252 is a great sounding amp in stock form but I believe these upgrades kick it up a notch.The remote is not original but a brand new SofaBaton universal remote. It has been programed for the MA 252 and everything works on the amp and remote as it should. You can also program it to control other devices in your system if you wish -- Just down load the app. punch in the make and model number of your device and sync phone/remote. It is a very nice unit. And last but not least is a brand new cover with the McIntosh logo embroidered on the front.All the original documents are included as well The amp will be will packed in its original box and packing material as well as double boxed for shipping. Please dont hesitate to contact me with any questions you may have. Thanks for looking!
