The amp is in great condition! All of the tubes look like they should and the metal is pretty clean with only some light pitting on it. See pictures for more and feel free to ask any questions! I’ve also included an invoice from an authorized McIntosh repair shop and the man who worked on it had worked for Mcintosh for 30+ years and knew them very well. The repair was minor and the goal was to have it work for another 40 years. The customer stated fault at the bottom of the document is misleading. There aren’t any problems at all with the power supply. This comment was made to the repair guy because that’s what my co-worker said happened to it. My diagnosis was unfounded and a guess. It ran like a champ when I used it! Also, the owner’s manual included isn’t the original but rather a copy of it that I have used.
