[quote=stryker59;6910]it is an attenuator that is inserted between the amp and the speakers. the amp sees it as a speaker load. the hot plate has different levels of db reduction....0, 4, 8, 12, and 16db reduction. what this does is allow you to crank a tube amp as loud as you want but keep the volume at sane levels. heres a link to the website:
