I have had an MC7200 for over 2 years now. It has operated flawlessly ever since I got my hands on it. But recently the right balanced input goes dead after 1-2 hours of play.
I know it's the input because I can still hear the hiss coming from the tweeter. I have powered down and swapped IC's at the back of the amp and the same channel remains silent, so I know it's not the output of my Cary 303/300 cdp. After just a couple of minutes of cooldown the channel comes back. But last night only 1 hot leg of the balanced connection came back (center vocal was shifted to one side). I had to power down and back up to get both legs back.
I plan on contacting Mcintosh next week to see if they have any recommendations. But I thought I would run it by fellow users in the meantime. TIA...
