I fully agree with Arthur! Have your McIntosh amp checked out by an authorized Mac shop. I now have two McIntosh amps, and both are completely silent during operation. I really don't think your 2505 should be making any noise.
Mcintosh mc2505 has a hum on the transformer......
I was wondering if it was normal to hear a hum on this amps
transformer?The hum is only audible when everything is quiet.Is this amp ready to retire?Another question is if the amp is on,and the volume is increased i can hear some hum in the background ,not too loud though?
