Lesvan, is the amp always that warm or only after a real work-out at high volumes? I do have the 402, but when not listening or only at low levels, it does not even get warm to the touch, only when I run it at 40 watts on large symphonies or rock do I feel the heatsinks to be warm.

Once I left it on for a few hours but it was idle, no music and it was up there with the temperature....... Mcintosh guy said to leave it on with no connections to troubleshoot other issues........ but it still gave off some noticable heat, it's warmer when hooked up and having music run through it. I noticed the transformer and heatsinks were warm, the autoformers were not. It was a demo that sat around for 3 years with out being used, out of the box but never connected or turned on.

I used to have one, and I don't recall it being that warm when idle, only when being pushed did it begin to get hot. However, I had it in a well ventalated/open location.
