You talking about these,
"
The McIntosh MC501 is unusual for a solid-state amplifier in that it uses an output transformer. This has three separate taps, one each optimized for 8, 4, and 2 ohm speakers. I hooked up my 8 ohm dummy load to the MC501's 8 ohm tap, and, following my usual practice, set the amplifier running at one-third power for one hour, to see how well it would deal with thermal stress. To my surprise, the McIntosh shut itself off after just five minutes—the orange Power Guard LED on the front panel illuminated, and the rear-panel heatsinks were too hot to touch. After the amp had cooled down, it turned itself on again. I tried running it at a lower level, just 30W into 8 ohms. This time it turned itself off after 20 minutes; again, the heatsinks were too hot to touch."
Wouldn't count too much on the meters, did you use the 2 ohm tap..,,
