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

I truly understand how you feel with the heat that comes with tube amps. In fact, that was the main reason that I switched from using them years ago to focus on solid-state amps.

I was never comfortable in my room because of the heat till I got a small fan that was always on when I was using the tubes. So, maybe I suggest you get a fan that you can keep in the room that can make the room cooler. I don't bother about those issues anymore because I run solid-state amps, and they give less drama, unlike tubes.
