I would like to know various challenges that some of us have had while using different tube amps. Currently, I make use of Evo 400, Mclntosh MA352 hybrid, and the Rogue Audio Cronus Magnum III.

I am the type that likes having different options when it comes to vacuum tube amps, but I've experienced different challenges while using these amps. For example, I always feel an increase in heat in the room when I switch from Rogue to Evo 400. That meant that I am always careful of the one to use depending on weather conditions.

So, I would like to know if anyone here run multiple tube amps and what issues you've encountered while using them?

Is there a good tip on how to manage heat, and how do you get along with managing running multiple amps?

I've only used one tube amp. But they're monoblocks. And they're OTL's, so the issue with heat in inherent with that topology. Though mitigated a good deal with the design I've used for about 20 years. But I simply don't use them in the summer. Why fight the electric bill with the AC. So I switch to my venerable old Hafler 220 I've used for 40 years. I do keep the tube amps on top of the gear cabinet. Unobstructed from anything
