    Hi all, I was just listening to my McIntosh mc250 and It started to make a loud hum and vibrate.. It is not related to any other equipment as I took it out of my system and plugged it into another outlet and it is humming and vibrating... and it isn't subtle. It did subside a bit when I moved it around and gently lifted a corner... Thoughts? Does it need to visit the doc?

    Yes, I am surprised the main fuse has not opened.

    Fuse or circuit breaker? At least that's what mine has.
