This 1964 McIntosh 225 tube power amp was a garage find of mine from a friend in Connecticut who bought it at a garage sale years ago. The amp was rarely ever used and found in not working condition however it comes with the original 1964 boxes as well as new boxes to protect the history of the original boxes.
Once purchased, I sent the amp to Audio Classics in Upstate New York and had a full functional restoration done. This includes replacing multiple capacitors in the power supply and audio sections of the amp. The high voltage and bias rectifier were replaced as were a number of resistors. New input jacks were installed and of course there is a completely fresh set of tubes with only a few hours on them at this point. Audio Classics warranties their work for 90 days of which there is about 60 days left. The amp is in PERFECT working condition. Beyond the Audio Classics warranty - there is no warranty.
Cosmetically, this amp is in original condition. There is pitting and slight rust where the chrome plated steel was bent. This is common of amps of this era from McIntosh Audio Classics says. Many of the markings on the back of the amp have worn off over time but its pretty simple to see where things should be plugged in. This is not a cosmetically restored amp as we feel that the amp's appeal is in its originality and its functionality. By all means you could restore the amp to perfect condition cosmetically if you so desire but we were more interested in what the amp could do in terms of performance thus the direction of the project. Honestly, I don't think the amp looks that bad considering its as old as it is nearing 50 years old but I don't want to represent it as a "100 point concourse amp" to use a car show term.
This is a unique opportunity to own a piece of audio history.
Please enjoy the photos that we took of the amp as well as the manual that Audio Classics made into a PDF. There are the original specs on the PDFs.
