There seems to be a mix of literature on the web proclaiming an attenuator will possibly ruin your amplifier, blw your tubes etc, and the converse that they are just fine. Anyone have a personal experience one way or the other? I'd like to crank my HRDx into creamy tube nastyness and not melt my neighbor's face off. (apartment living...) thinking something like the Dr. Z Brake Lite, says it supports up to 45 watt amps so I sneak just under at 40watts. Bring on the tales of flaming amp death OR complete apartment jammin' bliss as woman tone belts from the speaker in a happy and safe manner :-)
