I often hear complaints or observations about heat generated from tube amps. I'm curious as to which amps or tubes are the culprits here. I've owned two, working, tube amps an Onix SP3 using a quad of 5881s and my Shuguang which uses KT88. Neither produce significant heat in my estimation. Certainly not enough to avoid using in our hot mid-west summer months. I've used a portable thermometer to measure the air temp during and after use from a couple feet away from these amps and find no significant difference. So I wonder what are these "space heaters" and what kind of tubes are generating so much heat?
