Hello there, I just had my Mcintosh MC352 biased and checked out but it still runs a little hot..... I put an electric thermameter on the heatsink and it read 92 degrees. Chuck at Mcintosh said it should be fine but I'm wondering if your amp runs that hot too. It gives off heat like a small tube amp.

Mine runs cool at my normal listening volume and only gets warm if it's run hard for a while. It's never been hot to the touch. I think it runs very cool compared to other amps. Have you eliminated an impedance mismatch as the culprit?

I had the 352 and the 402. Idle neither were ever warm. After 4 to 5 hours or more of moderate sound level mine were always room temp and if warm not by much at all.
Heat was never an issue.

Hey guys, thanks for the feedback........I did not check my speakers with a meter yet, they're supposed to be 4 ohms....... I'll rest easy now, it seems some run hotter than others and the amp has a good protection system, so I'll just let it be........ I will say the heat is even on both sinks now, befor the checkup and bias only the left heatsink was hot, the right was very cool.
