Hi Guys! I just found a QST article on how to convert the HT-41 from 7094s to 572Bs- Does anyone have a pair of 572Bs in decent shape to spare? I am hoping to recap & convert my Hallicrafters Super Paperweight into a useful linear amp once again! (I also -still- need a pair of 866AXs for the rectifiers, unless someone has a good mod for them, too...) Thanks! Scott
