Reducing room TEMP. when using tube equipment.

Ron, why not invest in a portable air condition?

If it allows you to use your system when it's hot consider it money well spent on a "tweak".

I'm considering one myself. I haven't turned on my system in over a month 'cause of the heat. Listening while coated in a sheen of your own sweat and sitting in a pool of it is NOT conducive to an enjoyable listening session!

Oh, summer in the city! Yesterday it was 102 in Chicago, and 119 in my upstairs loft that houses my tube-based system. Needless to say, I didn't turn the music on last night. Tonight, however, is another story entirely. 85 outside and 93 in the loft. The amps are fired up and I digging the Op. 2 Sonatas of L.V. Beethoven.

Considering the temperature at which tubes operate, I don't think they'll even notice the weather. I notice it, though. And 8 KT88's, 8 6922's, and 2 5687's (the really hot ones) probably make my room just a little bit hotter.

Small sacrifice for L.V.B.

I worry more about humidity than heat. I should probably get air conditioning..........

Cheers.

If you can afford it, split a/c systems are available without the neccesity for ductwork. A handfull of manufacturers out there with efficient units. Email if you need additional info.

A potential problem with portable air conditioners would be the noise. You might be throwing out the baby with the bathwater.

Invest in some long cabling and move the units outside? :)
